Please include more information about how you have installed OctoPrint. We have no info on how it is running to try and give advice on troubleshooting or solutions.
I installed octoprint on a creality wifibox, following the procedure found on github. as said I am a layman and I thought the most sensible thing was to attach the LOG files, thinking, perhaps wrongly, that from them one could understand the problem.
I had a look through the OctoWRT GitHub, and there seem to be a few similar issues with varying resolutions, usually because some step of the install instructions was missed. Installing on the Creality WiFi Box is not common so I don't know enough about how it works to say what might be going wrong here.
And for the record, given how incredibly low powered (I'm tempted to say anemic) the aforementioned wifi box is, you should not consider it even remotely supported in either case. If it works, hooray, if it doesn't, well.
