URL rendered and opened on wrong port when 8888 already in use #1126
Description
Description
URL printed in console output (and automatically opened in browser) has the wrong port, if port 8888 was already in use.
Reproduce
- Ensure port 8888 is already in use on your system (e.g. by running another jupyter server)
- Launch a new jupyter classic server or lab
jupyter nbclassicorjupyter lab. - Server will run on port 8889 because 8888 is in use
- Error: URL printed in console and auto-opened in your browser will be port 8888, but the server will run on 8889
This happens with jupyter lab and jupyter nbclassic, but not jupyter notebook, which correctly prints + opens port 8889.
