Maybe it's related to #1006 I haven't tried the beta myself

dinojr commented 4 years ago

I don't thinks it's related

Also, the slide button/switch labelled "Connect" is greyed out and I can't switch it on even though the account parameters are set in the "Advanced parameters" menu.

@nikkopt this appears to be an Android permissions problem; have you granted all the requested permissions, or have some of them been withheld?

@jberkel patch #1009 would help by including the missing permission(s) in the log. Let me know if it's suitable or needs amendment (for example, would you prefer to set the error text in the constructor?)

I had the same issue with 1.5.11, with the "Unable to connect" error and the grayed-out "Connect" switch.

Despite having "Sync log" and "Extra debug information" checked, I get no log entries from attempts to restore.

I was able to enable restoring by watching the IMAP server logs when I made a connection attempt, and saw it complained "imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10)". I noted that I had a bunch of stuck logins for the server, so stopped and restarted it.

Once I did that, I was able to restore (well, it's currently still in progress, but has done about 6000 items so I presume it will complete).

Note that I was only able to do this because I use a server under my control. Assuming the server responds to SMS Backup+ with a similar error message, having that in the log would have helped me find this much earlier.

Thanks for the input. In my case, the problem doesn't occur anymore. I can now backup up as I used to. I don't really know what changed, except that between the last failed attempt (a few months ago) and the first successfull one (a few weeks ago) I broke my Pixel 3a broke and bought a new identical one... -- Julien Cubizolles

@edgewood thanks, that's a very useful observation.

I'll add "unstable network connection" to the list of things to check in this case, as that's the most likely reason for stacking up concurrent IMAP sessions.
