## Symptoms

- * After upgrading from R80.30 to R80.40 inbound inspection is not working and a blank page is showed, with a file "downloaded".
* Possible symptom: Instead of receiving the webpage, the client gets an error "Page cannot be reached" and gets an automatic download of a file called "download" which contains the letter "D" as its content.

## Cause

The upgrade from R80.30 to R80.40 was done with inbound HTTP/2 server. HTTP/2 server was configured in Destination of HTTPs Inspection rulebase, and certificates of the server were used for inbound inspection.
