Invalid character found in method name [0x120x010x00^0...]. HTTP method names must be tokens

I am using Java client to get data via web socket. I have a domain which is routed to my EC2 cloud.

Inside my EC2, I am terminating my https using reverse proxy of Let's Encrypt and routing it to my 8080 port as http.
Is there any issue in my ssl certificate?

I am getting data via web socket but sometimes I am getting this error:
"2023-09-28T03:57:08.504+05:30 INFO 3074 --- [http-nio-8080-exec-8] o.apache.coyote.http11.Http11Processor : Error parsing HTTP request header

Yes, seems like your local SSL cert issue. This thread might be useful.

But i am getting data from websocket but getting above error sometimes. The thread you provided says about different version and header size issue. But i think i am getting encrypted data. Does kite send encrypted data?

Kite Ticker sends binary data. You ca know more about parsing that data here.

Yes I know about kite ticker sending binary data. I am receiving data properly but only sometimes getting this error.
