Hi @GregoryShevchenko, thanks for the message. I am sorry for the trouble, it looks like the SSL certificate had some trouble getting installed on the root domain.
I have reached out to the network team to get their help to get this certificate replaced on the root domain. In the meantime, other forms of the domain will work, only the https://capsbutik.ru domain url form will raise the SSL error.
I promise to notify you as soon as the certificate is updated. Thanks!
