Hi, I’m having an issue that I can’t figure out. I have 1.6.1 installed on a machine with mint and one with win 7. Things were working in the past. Now the two devices continue to try to connect and then get disconnected after a couple seconds. Ive attached a screenshot of the gui on the windows machine. Seems network related, however in the console on the same machine I get the message:
info: connection to … closed
error: index update: arbitrary.file: file with empty block list
file changes as i pause different folders.
I’m on the same network and I’ve allowed the program in the firewall on each machine.
Please let me know what I can do, or what other info you might need.
Thank you very much
Interesting. I think you are right, except I did that and nothing changed.
Earlier today my linux machine had a very old version - 0.14 I think. I followed the instructions on the site, added the PGP keys, and updated - now I have 1.6.1 on both machines.
Except now that both sides are on 1.6.1 I’m actually interested in log messages if they talk about “file with empty block list” and you can provide some log details.
(I’ve anonymized folder ID’s below in case that matters)
Here is the log from the win machine (the file will change if I unpause other folders):

Here is the log from the linux machine that was recently updated to 1.6.1:

I guess it might be leftovers from the old version. You could try to remove the folder on the device that had the old version, restart and then readd it back.
Removing the folder sounds like it would probably work given all the feedback in this thread. I will try that later today.
However, I’m just curious if you have any ideas on other ways? I really like this software and this project, but the major downside for me has been the need to remove folders and rebuild them whenever an issue comes up. It’s like blowing on the cartridge or rebooting windows - not the most elegant, and in my case relatively time intensive because I have about 8 folders that sync about 1.5 tb.
Any thoughts appreciated. I will update when/if redoing folders works.
If you can zip up and share the index database from the lowermost machine I can take a look and see if there’s a visible root cause. Otherwise this “file with empty block list” is just something that Can’t Happen (and doesn’t, as far as I can remember seeing, outside of a couple of the 1.4.0 release candidates that you weren’t running).
