Service Temporarily Unavailable for WP login page?

What do you use for user restriction on that page – some kind of plugin?

Yeah a plugin called Page Restrict.

Try to de-activate it (not uninstall), and see if problem persists. If not, try to post on Page Restrict’s support forum, or just find another plugin that has the same functionality you need.

Im actually getting the issue without the plugin as well. Just doing a password for a page. After entering the password it will still come up with a 503.

Can you list other plugins you are using?

Contact Form 7
Greatives Visual Composer Extension
Page Restrict
Revolution Slider
WPBakery Visual Composer

Can you disable them all and see if problem still there?

If yes, it’s not plugin conflicts, so then it is most probably hosting issue and you need to contact them for assistance.

Disabled all of them and unfortunately its still happening.
I’ll get in touch with the host then. Thanks for the help.

Where do you host?
Because it looks like people are having similar issues with 1and1, see here maybe it helps: https://www.ads-software.com/support/topic/users-cant-logon-error-503-service-temporarily-unavailable?replies=35

Ha, yeah im with 1and1. I’ll check that out. Thanks!

Post your story/solution here when you have it, for other people having this in future ??

Will do!

I have the same problem with 1 & 1 hosting … same configuration with another hosting reports no problems.
