Are you running Docker/Portainer on MacOS, Windows, Synology, or some other Linux host?
Sorry, I'm running m4 mac mini. Also, I just quick using the node version and added as a stack and now I'm back up and running in Docker.
It looks to me like the node version is an alternative to using Docker on the mlbserver GitHub page. If you're trying to run both that would explain your port conflict. You need to pick a horse and ride it.
Thank you. I did. I'm going with the container version
OK, so then you should fix those two issues I pointed out:
I'd suggest this under ports:
ports:
- 9999:9999
And to fix the issue with your data not being persistent:
volumes:
- /Users/jasontrippe/mlbserver:/mlbserver/data_directory

Thank you. I’ll make sure I make the change.
Absolutely because same as last year and when logging into MLB it shows the subscription. But mlbserver won't get past auth.
It's running in a Docker container inside VirtualBox on MacMini. Worked perfectly last year and I pulled latest, rebuilt and fired up to this and then of course it exits. (I changed username/password to 'REDACTED' for this post.)
Edit: It runs as long as I don't try to login at which point it logs as below.
I appreciate any suggestions as it's so much more convenient than the app.

Do you have special characters in your password? You may want to try removing them: https://www.reddit.com/r/MLBtv/comments/1bq51lv/mlbserver_crashing_on_every_play_attempt_logs_say/
No, all numbers and upper and lower case (15 characters).
The team.tv is new this year of course and previously I had all teams.
Would it matter that my credentials.json has fav_team:""
Are others are using with single team purchase?
I don't understand it either. I have no idea what client_id is but could it be stale?
Is there anything weird with the network setup in your Mac/Virtualbox/Docker stack? VPN, DNS, etc.?
Can you try mlbserver on a different device for comparison? Perhaps just via Node or Docker directly in Mac OS.
The only thing weird is me. I looked at your code and tried your headers and form in PostMan and got same result. Then I determined I was using a vestigial password. I'm sorry to waste your time and kicked myself twice.
For me on the last two nights both Game Changer and Stream Finder show in the mlbserver webpage as available but only play the “event about to start” loop. Big Inning works.
Thoughts?
