Attempted Fixes

• Read on other issues it could be a memory issue with the fact we keep loosing connection. Using the top command I could see 2.8GB+ of ram free and the 4GB swap file we created untouched.
• Tried both Safari and Chrome to ensure we weren’t creating an issue with a certain browser. This was tried on both Mac OS and iPad OS.
• Read on other issues the auth could be an issue however after setting code-server --auth none it didn’t help.

Installed 3.5.0 on our Raspberry Pi 4 which is running Ubuntu and code-server has been working fine. No crashing and no errors in the logs.
