I have been using prodigy for a couple of weeks (annotations are increasing), the UI takes long time to load, but today it will not start altogether for a specific port and prodigy\_allowed\_session, other sessions and ports are working fine, am I missing something?  
I'd really appreciate the help. Thanks in advance.

Hi @aisha_harbi , perhaps the port is still running a process that's why Prodigy cannot connect to it? You can [check which process still runs in a particular port](https://www.tecmint.com/find-out-which-process-listening-on-a-particular-port/) and "stop" that. If it's Prodigy, just ensure that the data was stored / saved before killing the process.

Beyond that, it will be helpful to provide a log for this problem again. Maybe try passing `PRODIGY_LOGGING=verbose` then paste the log here?
