Thanks Sean!
Your are absolutely right, the certificates are OK.
Yes, the problem is that there were not anymore
any domains for several Site Routes - gone !!
We are working to add the disappeared domains
and to configuring them to corresponding Site Routes
as we did before this problem.
We are also invesigating why so many domains got deleted,
because
- all our sites were working 11th of May
- only smartban.dev domain
and the resources connected to it
should have got deleted
which we did verify
i.e. all other web sites were still working
with URL ref to smartban.dev deleted
ref:
"Order to update server configurations to delete an app powered by PHP-FPM"
