Re: Expedition - ML stuck at pending

Most probably the issue is that the Expedition VM has changed its IP.

Expedition does only allow connections from specific IPs, and one of those it's its own IP.

You can make Expedition configuration aware of this change by going to:

Settings->MLearning and setting the IP to the correct one and click "Save".

If the IP is already the correct one, set it "127.0.0.1" and click "Save". Expedition will automatically change the IP to the first interface IP and update the permits for this IP to be able to access MySQL.
