Thank you for opening this issue! The settings look good. Could you please capture the network pane of the DevTools while the error has happened? It should be indicated as a red line. Some more information about the DevTools is written here.

The same problem happened to me. I recreated the CouchDB on fly.io and synchronization was probably completed. But then, replication was not activated. The log is below.

023/6/18 1:54:09->LiveSync begin... 2023/6/18 1:54:09->Replication activated 2023/6/18 1:54:14->TypeError:Failed to fetch

On DevTool, 502 error returned.

I think that's server plan limitations and a huge, few GB vault that caused problem, anyone tested this while having a premium paid server plan?

[tyamanak]

my vault size is just 256mb and I've tried to do it again with the new fly.io account, but it didn't work as well. I went through the process with this doc (https://github.com/vrtmrz/obsidian-livesync/blob/main/docs/setup_flyio.md), and initial synchronization looked going well.

[vrtmrz]

Thank you all for the detail! Could you please check the metrics on the dashboard on fly.io? Perhaps memory had been exhausted. (Sometimes CouchDB uses a lot of memory to filter documents) Adding swap memory may improve this. Could you please try adding the command which enables that as like below:

fallocate -l 512M /swapfile 
chmod 0600 /swapfile 
mkswap /swapfile 
echo 10 > /proc/sys/vm/swappiness 
swapon /swapfile 
echo 1 > /proc/sys/vm/overcommit_memory

docker-entrypoint.sh would be appropriate. I made a sample as a colab notebook. Would you mind if I ask you to check this? https://gist.github.com/vrtmrz/37c3efd7842e49947aaaa7f665e5020a

I tried the colab, and it did sync successfully this time!

Thanks for the help :)

[tyamanak]

I've tried the process written in colab notebook, and it looks working well. But currently, is the plugin not working on mobile Obsidian? I can't set up it from scratch on my iPhone. anyway, thank you for your support!

[vrtmrz]

@tyamanak Sorry for being late! I am so happy to hear that the plugin working! However, the plugin should be able to be configured from a mobile device, even if it is the initial setting. Would you mind If I ask you about the trouble which is preventing configuration?
