And as app tells remove slash at the end of url.
Umh the strange thing is also in the first screenshots where the final slash was not present the error of character is so be sure to have not included spaces or other strange strings.
Also seems you are not forcing SSL, this can also be a cause of the issue: your chat still be loaded in http, I suggest to force https and this is server configuration.
You can maybe do this adding in the root folder an htaccess directive; you can look on Google how to do.
And as app tells remove slash at the end of url.
And try url like "https://chat.tatianatur.ru/index.php" as you are not using nginx configuraiton to support URL without index.php
]]>Today should be not difficult support HTTPS with let's encrypt certificate or maybe a cheap SSL service like ssls.com where i bought certificates in the past.
If you are not able to use HTTPS you can try to login by the web interface in a mobile device, app maybe will not work without HTTPS.
