OSError: Address "" already in use.
See original GitHub issueHi all!
I’m running into an error when trying to run app.run_server(mode='external')
Even if I kill all ports, and even if I change the port to a random number (for instance: app.run_server(mode='external', port=2000)
), the error still persists. I don’t know how to resolve this. Help would be appreciated! Thanks!
Full error:

app.run_server(mode=“inline”, host=“localhost”,port=8051)
so just pass different parameter port=? port number which is valid and not used I tried this it work for me OSError: Address ‘http://127.0.0.1:8050’ already in use. Try passing a different port to run_server.
The port busy error can also arise when you have two or more layout components that have the same id assigned. Usually the traceback will indicate a “DuplicateIdError” as well, but if you are importing layouts (e.g. from other python files) the only error that you might see is the “Address … already in use” error.
