Hi there,
Thanks for reaching out.
Error code: WEASEL typically signifies you’re encountering a broad networking problem. We recommend you refer to our Network Troubleshooting Guide to see if it helps resolve the issue. We also have an Advanced Troubleshooting Guide, if the Network Troubleshooting Guide did not help.
Error code Yam happens when your anti-virus is blocking Marathon's connection to your computer.
You can work around this by either disabling your anti-virus when Marathon and BattlEye are running or by adding those programs to your anti-virus' allow list.
We also recommend reviewing our Advanced Troubleshooting: UPnP, Port Forwarding, and NAT Types guide for additional solutions.
Just happened to me as well. Same issue with Weasel then Yam. And now can't get into the game. Just as I got the new weapon locker opened too.
EDIT: Adding that the additional information for me says: W:9:00002EE2 whatever that means.
