MVPHi @Ingo,
there is a change in behavior in 14.1. Please see:
K23237429: TCL error: ERR_NOT_SUPPORTED after upgrade to version 14.1.0 or later.
Try to add a if {[HTTP::has_responded]} to your iRule, as described here: https://clouddocs.f5.com/api/irules/HTTP__has_responded.html
This should fix your issue.

CumulonimbusDear Daniel,
thanks for the change in behavior link. I ran into this issue during our update yesterday evening from 13.1.5 to 15.1.8 as well. There were two different iRules in place, which both have a redirect command including a HTTP::uri condition. Connection was reset in the browser as stated in the article and the error count of the second iRule increased.
I could solve the issue by consolidating both iRules into one and separate its content with if-statements.
Now I know the reason 😉
But I don't find any hint in the release notes of version 14.1.0 for this. Or did I look at the wrong place? Just for future updates to avoid any issues due to behavior changes. I mean it makes no sense to check all relevant release notes, if not all behavior changes are included.
Regards Stefan 🙂
