I have rebooted the local server a few times and reloaded the example server.properties so it might have something to do with that. I havn’t updated since 0.27.2
@vshymanskyy interesting. @Jamin any chance you had old server running? Probably you just had the old config where hardware port wasn’t on 8080 port. Please report back in case you reproduce the issue again.
@James_Kelly if you take a look at the first post in the topic you’ll see that the OP provided quite a bit of information, was then asked for more information, and provided that also.
Your post tells us two things - you are getting a Packet too big error, and that you are using different hardware to the OP.
No mention of connection method, local or cloud server, library, App and server versions, serial output, sketch being used or when this issue occurs.
I’d suggest that you create a new topic which provides all of this information, and anything else that is relevant.
