Hello, so I have been experiencing this error for the past day and a half now. Specifically this bug occurs in both the Roblox Client and Roblox Studio.
It is extremely inconsistent with the bug occurring every 2/3 times I attempted to either join a game or open a studio. It also seems that some of the plugins I use in studio are having troubles with HTTP as well. Another sympton of this is while in a studio and I attempt to play test It only loads in about 1/5 times.
This has never happened in the past for me and only started up a day and a half ago.
I have already attempted the following steps to fix this issue with no success:
-Restarted My Computer.
-Restarted My Router.
-Flushed My DNS/IPConfig
-Reset my internet settings
-Reset my firewall settings
-Ensured roblox is allowed in my firewall
-Tried a different account
-Tried a different device
-Tried a different connection/IP
-Re-installed Roblox Studio and Roblox Client
