How do I fix the "SSL_ERROR_RX_RECORD_TOO_LONG" error for HTTPS access?
Issue description​
The error "SSL_ERROR_RX_RECORD_TOO_LONG" or "routines:CONNECT_CR_SRVR_HELLO:wrong version number" is returned for an HTTPS request.​
Cause analysis​
The HTTPS request was sent to a non-HTTPS port, for example, an HTTP port.​
Common cases are as follows:​
  • Port 443 of the CLB instance is bound to port 80 of the Ingress Pod.​
  • Port 443 of the Ingress Controller Service is mapped to port 80 of the Ingress Pod.​
Solution​
Check the access port and modify the CLB or Service configuration accordingly to ensure that HTTPS requests are routed to the correct port.​
