`error SSL_read: unexpected eof while reading` while running backup

[eliluong]

Hello, thank you for helping me with the previous issue. I let the process run to completion. Towards the end, however, I receive this error that I have not seen mentioned in issues yet. I can't tell if it's a particular email that is an issue, or if it's due to downloading such a large number of emails. Since I have delay_metadata enabled, nothing was saved so I would have to restart the entire process again. I have had this happen once before, but that was without verbose mode and I thought it was a one-time issue. Do you have any suggestions what I can try? Thank you.

Hi @eliluong

As this doesn't happen on previous messages, it's clear that the SSL-encrypted communication does (normally) work.

I suspect this may relate to rate limitation.

As you are fetching one message at a time ("multi_fetch_size": 1) you may be exceeding some rate limit after a while.

You may be able to avoid this error by increasing multi_fetch_size.

Also, are you sure that the reset_seen_flags_after_fetch flag is needed? Normally, it's only a requirement with Apple servers.
