Why does not enter the site (wp) after trying to enter the admin panel?

Question

Web development

An extremely strange thing happened to the site recently. I tried to enter the admin panel, after entering the password there was a long download, after which the page did not open. Now when you try to enter the site (not in the admin panel, but by direct url), it gives out "The web page is not available ERR_CONNECTION_TIMED_OUT". I logged in from a friend's computer - the site is working, all chiki-farts. I try to enter the admin panel, and again the site becomes inaccessible, both the admin panel and the main one. At the same time, everything is fine on every new computer. I cleared my browser cookies, I went from another browser, nothing helped. The strange thing is that when you try to access the site from your phone (which is connected to the same Wi-Fi as the computer), the site does not open. It looks like the router is blocking it. Never encountered anything like it.

Here I go with 3G and everything is ok:

Answer 1

Are you using the correct username/password? Maybe this is a block from brute force by ip. Well, try rebooting your router.
