503 error on WordPress Login – Host or WordPress?

  • Hi guys,

    I use WordPress for a number of sites & have never encountered this problem before.

    4+ sites still working ok, 2 effected. Everytime I go to; https://mysite.com/wp-login.php it will load maybe once and then on any refresh or after entering credentials it will immediately fail with a 503 Service Temporarily Unavailable (nginx) error.

    I’ve tried stripping my site down to basics – disabling absolutely all plugins and it still won’t have it. I’ve tried resetting my router, deleting cookies, using different browsers – the lot, no joy.

    Both sites are completely independent of one another and have different themes & plugins, but yet it’s not working.

    I’m stuck with Streamline.net hosting (God help me) and I told them about the problem after reading on the WordPress forums it’s server side and they’ve come back to me with;

    Thank you for your query

    We have been receiving multiple 503 related issues now and all of them have mentioned WordPress. Since WordPress has just updated, we strongly advise that you double check the settings of your browsers, plug-ins and other applications. Please be informed that 503 error is not caused by failure of our hosting services. We have tried accessing https://yoursite.com here in our end and it appears to be working fine. However, we will be giving you possible solutions to this kind of problem.

    Please be guided with the following:

    1. Clear your browser Cache.
    2. Uninstall unnecessary plug-ins and applications that may affect your website.
    3. Restart your router.

    If error continues, we advise you to contact WordPress and ask for assistance.

    Can anyone please, please help me or at least let me know if my hosts are blowing me off here!!

    Many thanks to all who read and bother to reply ?? It’s greatly appreciated.

    Sorry, it’s worth mentioning that mysite.com isn’t my real site URL! I just used it as an example.

    I saw a huge uptick in this with some other WP sites I manage. This always involved web hosts that were using nginx as a cache in front of Apache, and it always affected the site until the host fixed it. I was never told what they did to fix it, but any other sites hosted on the server would have the same issue.

    This makes me think it has something to do with nginx and/or some improper configuration on their end. Especially because the issue was always fixed without intervention on my part.

    Thanks for your reply, I appreciate it. Everything else I’ve seen points to that too, but it’s kind of my word against theirs.

    Will switching my MySQL database to a database outside of their hosting company resolve this and get around this issue or not?

    Ok, I’ve switched my own MySQL database and nadder! Awaiting a reply from my web host, I’ll keep everyone posted.

    Sorry for bumping – just posting a work-around I’ve found so anybody else in the future might be able to work from.

    I tried everything – resetting scripting, changing databases – the lot. In the end I changed the login page from /wp-login to /login using https://www.ads-software.com/plugins/rename-wp-login/ and that seems to be working absolutely fine now.

    Really don’t know what it was, but it’s working ok for me and may do for you, too ??

    I think I have the similar problem, after upgrading theme in wordpress, my admin site started show 503 error, I reloaded old version, but it did’t help…

    I want to try this plugin, but, please, where did you change the login url, when it is not possible to log in the admin site and use plugin there?

    Thank you

    Hi @bethem,

    From what I remember (it was nearly a year ago or so) the above plugin allows you to change the login url completely, so rather than yoursite.com/wp-login.php it can be yoursite.com/login.

    I don’t know what caused this error initially – but I was with a TERRIBLE hosting company. Since switching to TSOHost I haven’t ever encountered this again, so it might be worth looking at your hosting provider (especially if it’s a cheap shared hosting package) before trying to re-work your entire site!

    If you need to login & activate this plugin before the login URL is changed I believe I had to keep clicking login. Time after time after time it would simply hit the 503 error, but then once in every 100 or so it would load long enough to take me through to my dashboard. Once logged in, from what I remember, the problem is resolved. Activate the plugin, change the login URL and it should be OK?

    Hope this works for you! Well worth investigating the cause and your host too!

    Cheers.

    Thank you very much…

    It started to work somehow…:D

    I will change it and hope it could prevent any more errors:)

    Thank you again,

    cheers
