I’ve tried to solve my problem by reading previous topics, but that didn’t work.
Because of some proxy config in docker (I guess), all the people in our local network are seen by our discourse as coming from 127.0.0.1. 127.0.0.0/8 is whitelisted in “watched IP”, yet, we have a user who is unable to register, he gets the message I pasted in the topic.
There is no blacklist, at least one admin registered under 127.0.0.1, and everything was fine 'till now. I tried to remove the whitelist and to add it again, the error message changed, now it’s “max registration for this address reached”, or something like this.
Looking in our logs, we can’t find anything explaining why the whitelist is not effective.
Do you have any idea?
