Issue - Please wait before trying to login again

Some of my members are facing a constant issue. Snapshot below. Could anyone please help me understand why this is happening and which setting I should change to avoid this?

Facing this issue too, tried updating Discourse to the latest version, but that does not seem to be working. Please share a fix if you have found one.

Google login is working fine for the same people who face an issue logging in with username password. So, I have enabled google login alone on my website for now

Are there any errors in /logs you could share?
