The data we received from your Wordfence plugin installation is invalid.

When I try to log in first then add a site from wordfene.com, I’m seeing:

“HTTP 0 received from Wordfence Central”

OK, it looks like this is a webproxy blocking requests to wordfence.com

EDIT: Well, that was one part of the problem, but I still get the “The data we received from your Wordfence plugin installation is invalid” message and I can’t get a free license by adding it directly through wordfence.co

Hi @kwisatz

Thanks for reaching out!
Have you installed the Wordfence Plugin on your site yet?

If so, have you tried requesting the license from there?

Let me know!
Thanks,

Joshua

Thanks @wfjoshc.

Yes, I first installed the plug-in, then I clicked on “Get your Wordfence license” and then I end up with that message.

Strangely enough, I tried from another site on the very same server where it worked.

(I somehow didn’t get any email notification about your reply, despite having checked the checkbox.)

Hi @kwisatz

Any differences between the two sites? Caching? etc?

Let me know!

Thanks,

Joshua

No, there is no particular caching plug-in installed on the site where it fails. Nothing fancy otherwise either.

Can you disclose what makes the hash invalid? Or can I give you access to the site and you can check if you can detect anything that might make it invalid?

Hi @kwisatz

Can you try and request the license on this site again?

Once you do, can you send a diagnostic report to wftest @ wordfence . com? You can find the link to do so at the top of the Wordfence > Tools > Diagnostics page. Then click on “Send Report by Email”. Please add your forum username where indicated and respond here after you have sent it.

Also let me know here the approximate time including timezone you receive the error message.
Thanks,

Joshua

I just did.

I also see here that it claims that it can’t connect to one of your servers, but that’s not the case anymore. It was at first, I have since then authorized *.wordfence.com in the proxy settings.

Edit: Oh, I see that it’s trying to use http… hmm, I didn’t authorize that indeed. I’ll give it a try, just to see if that changes anything.

Edit2: No, it doesn’t change anything.

Hi @kwisatz

In the new error message about our server that you receive, where there any cURL numbers?

If so, which ones?

Thanks,

Joshua

No, there’s no numbers, there’s just the message.

I recorded a video : https://cloud.tentwentyfour.lu/s/pcoNDAYCM46CQ9y

Hi @kwisatz
Thanks for sending that over.

Approximately what time was that video recorded at and which timezone?
We need this information to further locate this error.

Thanks,

Joshua

@wfjoshc that was around 6:30 pm CET.

Hi @kwisatz

I took a look and I can see that the site is identifying itself as a domain like “new.example.com” and the admin URLs for the site only “example.com”.

Wordfence currently expects these URLs to match.

In the meantime, if Wordfence was originally installed on a test copy of the site with that alternate domain, it may be necessary to remove the plugin, choosing the option to remove all Wordfence data, and then install it again.

I hope this helps!
Thanks,

Joshua

Thank you @wfjoshc, changing those values in wp_options did the trick!
