Hi again,
Well I mentioned in other thread some errors I get.
They are below, maybe they can help to identify the cause of the problem:
Exception on /dns/dump [GET]
Traceback (most recent call last):
File "/usr/local/lib/mailinabox/env/lib/python3.10/site-packages/flask>/app.py", line 252>
response = self.full_dispatch_request()
File "/usr/local/lib/mailinabox/env/lib/python3.10/site-packages/flask/app.py", line 182>
rv = self.handle_user_exception(e)
And:
xception on /dns/dump [GET]

Thanks once again for your help.
P.S.: I also found the below lines in /var/log/syslog. Just after I tried to access the External DNS page (obtaining the 500 error):
