Yes, after all the tests, we can practically say that the server is the problem, but we need their confirmation, I wait for the news.
If it still doesn’t solve it, don’t worry because our community is open and I can let another expert with more ideas try to help you, but before that I need to be sure, because if they confirm a problem with the server, it doesn’t help any more solutions to be passed on to you, because the problem is probably in the site server.
Until later.
Graciously,
