First, purchasing the Season Pass would not suddenly cause you to have connection errors. Second, [b]disabling Cross-Save will not fix your issue[/b], and you'll be locked out from reenabling it for 90 days. Don't do it if you have Cross-Save set up the way you want it. If you've been connecting fine and suddenly started having issues, especially Weasel error codes, that's a sign that your end of the connection cannot fully connect and stay connected to the Destiny 2 data servers. Weasel is specifically a code that's entirely connection-based. Because it's a sudden change, that implies that it might be a hardware failure issue somewhere either on your local network, or on a hop outside of your local network between yourself and Bungie. If your ISP regularly sends updates to your modem, that might also lead to an issue if an update closed off one or more of the ports necessary for Destiny 2 to connect. You should contact your ISP while playing the game and getting the errors to determine if there's any issues with your internet connection at that time. The issue is either on your end specifically (your computer, local network [your router/modem and cables]), on your ISP's end (the connections and hops in their own network), or sadly, outside of your ISP's end. If it's on your local network or computer, you can follow the networking and troubleshooting articles Bungie has provided. If it's on your ISP's end, you'll need to work with them to inform them there's an issue and have them fix it. If it's outside of your ISP's realm of influence, then you'll need to wait until whatever company owns the offending set of hardware to fix it.
