Current version in use is Extension shows as version (web filter)


Error is just:

Here is the latest from support:


Looks like this ZSTD is implemented in FortiOS for other uses, but not for inspection. This means that the inspection profiles applied to a policy that is supposed to allow the zstd-encypted sites will fail and the browser will display an error instead of the website's content encrypted with ZSTD.


New Feature Request is already in place and we still do not have a specific date for it, so we will have to accept the work around that is documented at the article reference given below.
