Error while gettind updates

[eljdos]

Hey there,

Thank you very much for the hard work :)
I really love the project !

I have a recurring error - it doesnt prevent the bot for working though - that I can't get around.

Every few seconds I have the following error message : telegram.ext.updater - ERROR - Error while getting Updates: Conflict: terminated by other getUpdates request; make sure that only one bot instance is running
2020-01-04 22:30:08,264 - telegram.ext.dispatcher - ERROR - An uncaught error was raised while handling the error

Any chance you might have already seen that ?

Thank you again !
