I guess we could improve the error handling here.

Marking this S-Critical since it incorrectly tells you to throw away your session, which could lead to data loss

Coming from https://github.com/element-hq/element-web/issues/27622 this doesn't have to be spotty network. This sometimes happens also with good/stable network. I assume it might be in the right moment when develop is being redeployed, maybe. Though I have no evidence of this actually being a true assumption.

Yeah if it happens more often on develop that is not something we'd consider fixing. Develop is known to be unstable and for development.
