The reason is that your IPv6 2a05:541:112:31::1 is not accessible. Did you check port 9001 on IPv6 from the outside?
Thank you, I did not check indeed. Something has probably changed on the provider side, since no configuration has been changed in the recent weeks, and weirdly enough the server can still exit in ipv6, but does not answer to pings from outside. I have temporarily disabled IPv6Exit and the respective listening ports while we investigate.
