Hello!
No I don't think so, I recently had a page with the Templ Layla from J 4.0.6 to J 4.1 for testing. updated.
This is surely a problem that has to do with joomla itself, your provider or other things!
What error message do you get exactly?
(In the config. settings: Server - set "Report errors" to "Maximum"
From which country do you come ?
Here is a very good German Joomla forum:

maybe your problem is already there! use search...
Best regards
