Website loading problem, how to solve?

Question

PHP

The site waits for a response from the server for 30 seconds during the transition and the same on all pages. Login to admin is fine. When contacting the hosting staff received the following response:
Hello. When executing the index script of your site, we observe a long connection to a third-party server - 195.154.241.86: connect(8, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("195.154.241.86")}, 16) = -1 EINPROGRESS (Operation now in progress) poll([{fd=8, events=POLLIN|POLLOUT|POLLERR|POLLHUP}], 1, 60000 Regarding the observed problem, you need to contact the site developer. From our side, unfortunately, analysis and editing custom code is not implemented.Visual
Composer also began to work incorrectly in the admin panel.I've been
fiddling with this problem for several days, I don't know how to solve it

Most likely your WP has been infected. Look for backdoors, scripts. Restore from backups.

And yes, third-party modules are often vulnerable in WP

Answer 2

First of all, check header.php and footer.php - there is most likely a line
After cleaning, configure the correct access rights to the folders through the hosting. I also advise you to put double authorization on the admin panel, i.e. htpasswd (google for this word). Check the list of users in the admin panel, if there are extra ones - delete and change passwords for all!
