Sync consistently times out

I have set up Lieer successfully in two other Gmail accounts with less emails. However, the last one with over 100k emails consistently fails with the following error during the initial sync. The stack trace looks like the HTTPS connection somehow drops in the middle which Lieer doesn't expect and there's no retry. Not sure if anyone has seen this before. Is there anyway to work around this?

I'm using Lieer 1.3-6 with Python 3.9.5 on Ubuntu 22.04.
