OS: Linux/Ubuntu 20.04.2 LTS (Focal Fossa)
Nim Version: 2.0.8
Clients Tested:
Windows w/ Chrome
IOS w/ Safari
Issue:
The header of a websocket packet is being scrambled somewhere between the client and ws recvFrame. Chrome dev tools sees no issues with the packet released but I get rsv mismatch on the backend. I tried blotting out the rsv check to see if the error was in the client enabling the rsv flags for some reason but the OPCODE was messed up too. I wasn't able to check the body as ws doesn't read that till a later phase. I have no idea how or why this is happening.
Note: This may not directly be a ws library issue but it is related and this seemed like the best place to ask
