Wall of text incoming.....I'm truly sorry :( Unfortunately all of those error types are networking related - which SUUUUCKS....genuinely.....diagnosing general networking issues......SUUUUUUCK. All the issues being anywhere from Bungie server side > Steam server relays (remember the Beaver epidemic - was caused by Steam relay issues) > ISP > Local infrastructure > Your hardware > Software. Troubleshooting your own hardware and software are the steps you have the most control over but are also the most tedious. Here are some things you can do to be very confident that the issue is outside of your control: 1. Make sure your router is setup to allow programs like D2 & Steam through properly and is not blocking your devices programs, this is helpful for all platforms - Bungie has a link for the particular settings needed: https://help.bungie.net/hc/en-us/articles/360049496751-Advanced-Troubleshooting-UPnP-Port-Forwarding-and-NAT-Types 2. Check the condition of hardware at your residence, i.e. ensuring ethernet plugs and power cables and inserted correctly and have no damage to them, your platform of choices' components are functioning properly (for PC making sure that hardware passes testing and health checks from reputable diagnostic tools - ESPECIALLY networking related components due to the type of issues you are facing). Environmental factors are also at play if you are using WI-FI as other signals (bluetooth, WI-FI, microwaves) can interfere with the quality of your connection. 3. Check software health - If your hardware appears solid you want to ensure that the OS you are running is healthy and up to date, after that there's a slew of things to check (most relevant to PC): - signs of malicious software - driver updates - steam installation integrity - aggressive anti-virus interrupting network connections - sleep & power settings for your network device so it doesn't reconnect every so often - firewall settings in the OS which are blocking D2 from accessing the internet properly So after ruling EVERYTHING above out - You are at your house with a fully working, completely clean, 100% healthy device with a working OS and game installation, drivers are up to date and the home network is strong and has no interference.....You hop on destiny and........BAT/ARUGULA/SPINACH appears...... After resisting the urge to destroy all your belongings in your general vicinity, the next step you can make is to call your ISP and ask them to do some line testing due to networking issues you are having - which may identify physical issues on the line between you and your provider. The phone interaction with your ISP may vary (so might their technical expertise) and they can only use diagnostic tools they have access to (so be nice to them, even if they don't end up helping), so this is potentially a fruitless endeavour but it is a failure point which should be addressed. So now you have a Tested known working device, inside a known working home network, connected to a known working ISP connection.....hopefully SOMEWHERE in there your issues are resolved, if not......it's completely out of your control to influence and reaching out to Bungie and Steam through the help forums and social media are kinda your only recourse. If there are ANY steps above you are unsure or hesitant about trying I STRONGLY urge you to reach out to professionals in the Computing and IT field (either online or local) to help you learn / assist in diagnosing the issues. This is why General Networking issues suck Thank you for coming to my Ted Talk.
