HaaS proxy ... SSH warning

I have recently registered a bug in the HaaS-proxy process. The error occurs sporadically cca 2-4x a day

Mar 12 09:23:15 Turris_JB haas-proxy-start[5031]: 2023-03-12T10:23:15 WARNING twisted Can't handle environment variables for SSH avatar <haas_proxy.proxy.ProxySSHUser object at 0x325a7c8>: <haas_proxy.proxy.ProxySSHSession object at 0x3553e98> does not provide ISessionSetEnv interface. It should be decorated with @implementer(ISession, ISessionSetEnv) to support env variables.

Not only this error…I noticed some time ago (and, if I remember well, reported it) that HaaS log is full of errors like

2023-03-01T04:35:05 CRITICAL twisted ‘channel open failed, direct-tcpip is not allowed’
2023-03-01T04:35:08 ERROR twisted Got remote error, code 11

As far as I don’t know what to do, I’m ignoring them… Maybe they are, in my case, temporary only. Anyhow, HaaS seems to be working, in spite of these errors
