Nimbostratus[WSS ] illegal URL
Hi I am getting the following msg (Blocked) in event logs [WSS] illegal URL ANy idea abou it. Using version 13.x
Mike_275667The transaction must be a false positive. Did you try to learn the suggestion? Go to, Security >> Application Security >> Traffic Learning, find the URL that is blocked and try to learn the suggestion
MSZPlease review the question again. This URL is working properly with HTTPS. I am getting blocked requests with WSS

ASA MSZ,
It seems that your application use Websocket.
- WS (for unencrypted text)*
- WSS (for encrypted text)
As for HTTP/ HTTPs URLs, you will need to specify within your ASM policy "Allowed Websocket URLs"
You can define allowed URL either using "wildcard" from :
Security ›› Application Security : URLs : Wildcards Order : WebSocket URLsOr explicitly from :
Security ›› Application Security : URLs : Allowed URLs : Allowed WebSocket URLsHope it helps
