Autest tls_tunnel fails because of a slightly different error message from python

[maskit]

test proxy_protocol_port - not in connect_ports fails, because it can't find "ssl.SSLEOFError" in the output.

The expected error message is probably like this

ssl.SSLEOFError: [SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1006)

but the error message can be like this (it probably depends on the version of python or its library)

ssl.SSLZeroReturnError: TLS/SSL connection has been closed (EOF) (_ssl.c:1129)

Is this related to #9550 ?

Yes, looks like the same as the issue you reported. The one Masaori mentioned seems like a different issue.
