I have a bunch of client sites running sitefinity 6.x
Whenever IIS is reset, all the sitefinity client sites seem to lose their licences? The users and site visitors are directed to the licence activation screen. Is there any way to stop this? It's driving everyone mad including me.
It is well know issue caused by .Net framework 4.7

Telerik is providing hotfix for all Sitefinity versions 7.0+
Best and single way to solve your problem for SF 6.X is to upgrade to any version 7.0+ which included this hotfix.
My clients have not maintained their subscriptions, so I can't upgrade them.
Is there no other fix for this?
