Hi @lastsplash

” … I wonder if it is running into rate limits … “. Imposed by who?

Hi @lastsplash

How do I upload a screen shot? Or can I send it to you somehow?

I had a friend open the page on her computer and she is seeing what I am eg. three greyed blocks with question marks on a small blue tile. This cannot be caching because she hasn’t opened the page before.

Hi @lastsplash

I have encountered another load problem on a fourth TG I have built today. This has been added to the test gallery as well. This image is captioned “Shore House, Burnham On Crouch, Essex”. It is 199kb JPEG.

Hi @lastsplash

I took your advice a reworked the above image to a smaller JPEG. There were a couple of others I also updated for the same reason (GIF > JPEG). It hasn’t changed anything.

Ever the optimist I tried creating another new Tiled Gallery and that has worked fine, so I created a third. While working on this last gallery I have again hit the problem, this time with a 299kb JPEG.

I have removed the image from my ‘real’ gallery and added it to the test gallery (https://www.nigelware.photography/?page_id=739). I have also updated that gallery removing all the successful images, leaving only two that will not load. Both of these are JPEG, with “Sea Fret Low Newton” being a reworking of one of the GIFs as you suggested. It is only 100kb. The other is the new image which was uploaded today.

Hi @happyaxident

After reading your reply I waited 2h 44m before trying the pages:

https://www.nigelware.photography/?page_id=739 has two images that are not displaying. This page started showing a 10th image (see above) in the last 2 / 3 days. Clearing the cache does not seem to have improved things.

I cleared my browser history before testing and after that didn’t work I also tried in a Private Window without success.

The two images concerned cannot be loaded directly into a browser window. Both giving a 400 error

Hi @jeherve

I have received this reply from EasySpace:

We’ve been investigating the IP addresses that Jetpack sent us and indeed we are seeing some hits to the server logs mentioning “Photon/1.0”?

/var/log/nginx/access_log.6.gz:www.nigelware.photography 195.234.109.174 – – [21/May/2024:10:52:36 +0100] “GET /wp-content/plugins/jetpack/_inc/blocks/images/tiled-gallery_example-6-9f9d39c6af0fb4b0d99c.jpg HTTP/1.1” 200 7281 “-” “Photon/1.0”

We can confirm none of their IP’s are blocked on our end at the moment however Jetpack has a cache plugin called wp-super-cache that’s associated with it and also an internal cache plugin.

Can you try clearing these to see from your wordpress admin if possible to see if Jetpack is maybe caching some of the images with an error message or possibly check with Jetpack to see if they cache any results on their end that they can clear?

In their last two paragraphs they write “Jetpack has a cache plugin called wp-super-cache that’s associated with it and also an internal cache plugin.” and ask “Can you try clearing these to see from your wordpress admin“. I have had a look around JetPack on my dashboard but cannot see any mention of cache. I did find a link to WP Admin but couldn’t find anything about cache there either. Where can I clear these two caches, please?

They also ask “… possibly check with Jetpack to see if they cache any results on their end that they can clear?“. What can you tell me?

hi @jeherve

I have passed your comments, above, to EasySpace and am now waiting for their reply.

Hi @jeherve

https://www.nigelware.photography/?page_id=739 is now showing 9 of 12 images. 3 days ago it only showed 8 and 7 days ago 4. If the images are gradually loading can EasySpace really be blocking your agent?

Hi @jeherve

I have an open ticket with EasySpace about this situation and have been copying your suggestions to them. Here is their latest reply.

I don't think this is an issue on the Easyspace side, as we would be hearing from more customers if there was an issue at our end as Jetpack is one of the more popular plug-ins used.

I have flushed the varnish cache for the site and reloaded the page in my browser, some images are loading while others aren't that are getting served from the same place.

For example these give the 400 message:

https://i1.wp.com/www.nigelware.photography/wp-content/uploads/2024/03/FramlinghamJoustSwords_0925_3x2.gif?strip=info&w=1500&ssl=1

https://i2.wp.com/www.nigelware.photography/wp-content/uploads/2024/03/OrfordCastle_3672_4x5.gif?strip=info&w=878&ssl=1

While these load fine:

https://i0.wp.com/www.nigelware.photography/wp-content/uploads/2024/03/MinsmereStag_4295_4x5.gif?strip=info&w=877&ssl=1

If the issue was us blocking communicating with the CDN then it would follow that no images would load from them, not some images.
The ones giving a 400 message also show this when trying to access them via a web proxy.

Had a look for photon in the logs for the site since that's what Jetpack support says we should be checking for and couldn't see any mention of it either, the extract below is from wphost2-7 since that's what I was hitting when testing.

[root@wphost2-7 ~]# grep -l nigelware.photography /var/log/nginx/* | grep -i photon

There is nothing in the php-fpm error log for my visit.

Towards the end of that reply EasySpace are saying that they are not seeing any activity for agent Photon/1.0

I also note that EasySpace say “The [images] giving a 400 message also show this when trying to access them via a web proxy”. Which is my own experience.

So that I am clear are you saying that the images cannot be loaded to your server from EasySpace because of a block?

hi @alinclamba @jeherve

Today I have created a new tiled gallery “https://www.nigelware.photography/?page_id=788” with 9 different images. Again the page is not visible through the menu system.

These 4 images displayed immediately after page creation.

After allowing a hour for replication there is no change.

hi @alinclamba

Page https://www.nigelware.photography/?page_id=739 was created on 12th April 2024. Until 4 days ago no images displayed on the page. Then 4 of the 12 images started to show. Today 8 are showing. Thats 66% success in 39 days.

The image URL below (which is one of the images that do not display) gives a 400 error when pasted into a browser address bar. This has been tested on multiple users browsers to avoid caching issues.
https://i1.wp.com/www.nigelware.photography/wp-content/uploads/2024/03/FramlinghamJoustSwords_0925_3x2.gif?strip=info&w=1590&ssl=1

Developer.mozilla.org says that “400 Bad Request response status code indicates that the server cannot or will not process the request”

EasySpace also say that a 400 error “would indicate an issue with the remote server hosting the cached images”

If 66% of the images on the page are now loading how can it be that the “..hosting provider currently blocks all HTTPS requests coming from one of our CDN’s..” As suggested in a previous reply on this ticket?

Hi @jeherve

I have a further update for you. Without me changing any settings (CDN is still off) 4 of the 12 images have started to appear on the test page https://www.nigelware.photography/?page_id=739

Hi @jeherve

EasySpace have come back with the following reply:

“..we would need to know the IPs that Jetpack believe we are blocking..”

Hi @jeherve

I have contacted my hosting provider, EasySpace, about this issue and am waiting for a response from their technical team.

Hi @akumarjain @happyaxident @alinclamba @erania-pinnera

” .. Could you temporarily switch to a default theme .. “
I have tried switching to themes 2022, 2023 and 2024. The results for all three were the same. Only the Jetpack Plugin was active during these tests.
With CDN ON: No images appear anywhere on my site:
With CDN OFF: Image appear everywhere except on the Jetpack Tiled Gallery

 ” .. checked the page source of your gallery pages and couldn’t find the Carousel libraries .. “
I am not sure what it is you are looking for.

” .. Health Check & Troubleshooting plugin .. “
There are 6 notifications, 4 security and 2 performance, 1 about “No page caching detected” and the other “Outdated SQL Server”.

“..The problem could also come from a missing wp_footer() function in the footer of the theme..”
I am not sure where I would look for this.
