After investigating, the wiki NynthiDB (https://nynthidb.miraheze.org) currently has two files for which it is impossible to load them even by directly going to the source file in the Static Miraheze URLs.
The following are known to be clearly bugged out and are to be fixed:
The others files seem to load in some way, but these two are giving "Service Unavailable The server is currently unavailable. Please try again at a later time.".
If you wish you can check if there are other broken files but the rest seems fine on my side.
Thanks to fix them
