I installed my mastodon server, can federate, everything works great except following a RSS bot that I’m running on a local docker behind a firewall, using Let’s encrypt certificate. Browsers report no problems and can reach the bot fine. Other Mastodon instances can correctly follow the bots as well.
I got exactly one mention of an error in the bundle log:
Switching source:82.64.XX.XX from green to red because OpenSSL::SSL::SSLError SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate) on https://rssbot.xxxxx/u/YYY
I’ve modified my configuration and get an A label from ssllabs.
The logfile shows no mentions of errors any more but the user interface shows “error 503” when I try to follow one of the bots.
I presume that the IP is in some kind of a blacklist because of the earlier error? How to remove/whitelist? Is there a scheduled check?
Is there a way to overrule the “cache” that seems to exist for the “bad” IP?
Thanks for your inputs!
