Recently we've started experiencing problems with logging in to Polygon. Access attempt from internal university network(KFU) results in eternally checking our humanity. Accessing from other networks is possible but takes some time for Cloudflare to give us a captcha. Moreover logging in using Polygon API returns a response with 403 code and I suspect that the reason is the same(we use client by [user: PavelKunyavskiy]).

Could maintainers take a look at this please? I can give more details in DM

In recent days I can't view problems page of some contests as well as View Problems tab on the top. Meanwhile most contests' view works fine. Also some parts of API also fail so that I can't use polygon-cli tool from Pavel Kunyavskiy(specifically it fails to download packages which is done by API and to find a problem by an id which is done by parsing the website).

The same troubles have my colleagues but I checked another old account and found that there are no such issues. I wonder if there are a lot of people who encounter the same problems as I do.

I have no idea how to deal with these problems. What makes things even worse is that I can't find any place to report a bug or ask for a support.
