my server is running in a different timezone and I started getting this error in the log exactly at 6 AM:
2020-01-01 06:00:21.613 [error] <0.2582.0>@ejabberd_auth_external:failure:103 External authentication program failed when calling ‘check_password’ for derek@mydomain.com: disconnected
Any help would be greatly appreciated as this is my primary method of chatting and receiving SMS!
Sorry for the lack of detail on this. When trying to edit the network to solve this issue I ran into other problems.
There were no configuration changes before this started. I looked closer at the log and the entry is actually like this:
2020-01-01 06:00:21.613 [error] <0.2582.0>@ejabberd_auth_external:failure:103 External authentication program failed when calling 'check_password' for derek@neth.mydomain.com: disconnected
So we can see that for some reason it is trying to auth with the Nethserver subdomain in the username, even though usernames are like derek@mydomain.com.
