How to set up Yandex disk via HTTP proxy after the update?

Question

Yandex.Disk

After the next update (about a week ago), the Yandex disk client through the proxy stopped working, constantly being in the "data processing" state. Search on the Yandex website and technical support answer (the same):

... add access to push.yandex.ru server and port 443 to exceptions. ...

But here's the thing, my proxy does not restrict me by domains or ports (all the same for myself ...)
Correct me if I'm wrong, but if the client needs to go through any domain, he does it, for any , and if he needs a new server, then you just need to go to it ... this should not affect the mechanisms for transferring information from the client to the server ...
Squid3 proxy, part of the config:
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
http_access allow localhost
http_access deny !
Safe_ports

Answer 1

Update the client, version 1.4.9.5195 dated 07/10/2016 - works (at least with squid/3.3.8 and squid/3.4.8)!

Answer 2

Rollback to the previous version of Yandex disk 1.4.7.5052 helped me.
