Update to 0.52 does not show any backups at remote location

for a few years I am running now mail in a box with rsync backups over port 1355
to my home NAS, for this I commented out following

first line is commented out, cause that caused issues
and than the 2nd line to the port

“–ssh-options=’-i /root/.ssh/id_rsa_miab’”,

“–rsync-options=-e “/usr/bin/ssh -oStrictHostKeyChecking=no -oBatchMode=yes -p 1355 -i /root/.ssh/id_rsa_miab””,
]

update, for what I see is that the backup is valid and I see that there is communicated with the remote site, but Mail in a Box is unable to show the backups made. And then gives an error (unknown error)

the ./backup.py – verify shows that it is actually making an verifying backups perfectly.

So the question is why backup.py cannot show the backups in the GUI from the remote site.

Have a look at:

for similar issue.

That is not the solution

What I see what is happening is that with the proper change the backup is stored
but mail in a box is not able to show the content of the backup remotely anymore, so the ‘available backups’ are not shown anymore

Also I see further at round 70% of the backup.py another rsync line …

reboot of the machine solved the issue
