Disappointed me

Unless I used to test login in the incognito window before log out, I would be locked out.

Hi,

The HTTP 503 error code from a webserver means it is currently experiencing capacity problems, unrelated to the plugin (see: https://httpstatuses.com/503).

Hi David,

The website is on a VPS with a lot of space, so it isn’t a capacity problem. I’ve switched to another 2FA plugin and it works fine.

There is another thing that might lead you to the problem. My website is on a subdomain and used Cloudflare service.

Your plugin looks simple and good, this what encouraged me to try it, try to fix this problem.

Hi,

Neither being a subdomain nor being on Cloudflare can cause a webserver to decide to emit an HTTP 503 code. To find out the server conditions at the time, you’d need to speak to the webserver admin so that he can investigate the logs. There’s literally nothing to look at in a plugin for that: as I say, the code’s defined meaning is that the webserver is telling you that it had a capacity problem at that moment.
You mention being on a VPS; in fact, if it’s an entry-level one, that actually makes instantaneous capacity problems more likely than shared hosting, because then you have a single CPU being shared across all the operating system, background resources, webserver, database server and PHP engine.

(Edit: deleted comment: made a suggestion that was not relevant to this plugin).
