Odd problem

I have a very odd problem in my Android app. When I stress test my network solution (Mirror) I sometimes get a problem that ends up with the app looping forever and is unresponsive. I have searched for this problem for a long time without success. The only thing I can see is some log entries in logcat and they doesn't say much.
But I did finally realize that I2.Localizer is mentioned in the call stack of the exception logging, I haven't a clue why. Does the following log entries give any ideas for what is going on?
The first problem seems to be the EndOfStreamException (logged once), after that there is an eternal loop where the NullReferenceException is logged about 3-4 times a second.
The "I2.Loc.LocalizeTarget" mentioned in the log entries - is that the normal call for localizing a text or is it some internal housekeeping thing?
By some reason I can't debug the code remote and the problem is not present when I run in the Unity editor. I haven't a clue where to start look for this problem. My guess is that it is a Mirror problem, but if someone can explain why I2.Localizer is involved in the logging I might have a chance to get closer to where the problem is.

Hi,
It looks like you serializing an object into a stream and then de-serializing the object in the client.
But the stream got corrupted, because the object was created (and that object has a Localize component inside), But the stream was empty (len=0) so the de-serializer was unable to initialize the object values.
It just happened that the LocalizeTarget is one of the first components in that object.
Hope that helps,
Frank

Hi,
None of the objects that are serialized/de-serialized include a Localize component. And in the situation where the problem arise there is only a very basic poll/response thing with static text going on.
The odd thing is that LocalizeTarget is mentioned at all, and the Sort() method is also mentioned. The only place in my entire solution where the Sort() method is used is in I2 in the Editor and in the Google sections.
The problem is most likely to appear when the app in just started which make me suspect that the synchronization of the Google sheet somehow interferes with my Mirror based device communication. What port(s) do you use for the Google communication?

Hi,
I'm having a similar problem. Did you find the solution to this issue? Please do respond.
The app works completely fine on the editor but it's causing the trouble on Android and iOS devices.
