Broken login in Chrome

[v1adko]

Can't login (and thus can't submit an entry).
After authenticating the Telegram account nothing is happening.

OS: MacOS Mojave 10.14
Browser: Chrome - Version 71.0.3578.98 (Official Build) (64-bit)

Bot is authenticated:

Can you try with a different browser?

[v1adko]

Incognito in Chrome does not solve the issue, so we can rule out extension interference.
Safari Version 12.0 (14606.1.36.1.9) Works
Opera Developer (Version:59.0.3192.0) Works

All of the browsers are the latest versions available right now.

So it does work on Safari and Opera but not on the latest version of Chrome? I'll try to reproduce.

Works for me with the latest version of chrome. I'm not sure how can I debug or reproduce this problem, try clearing cache maybe.

Isn't incognito is the same as having fresh cache?
Telegram auth cookies are set correctly, however UI ignores the aouth callback.

Can you inspect Chrome's network tab and see what the request to Telegram server and then tgdr server returns.

error: "NOT_AUTHORIZED"
html: "<button class="btn tgme_widget_login_button" onclick="return TWidgetLogin.auth();"><i class="tgme_widget_login_button_icon"></i>Log in with Telegram</button>"
origin: "https://tgdr.io"

Hmm maybe you declined the permission to login in the message that was sent by Telegram to you?

Hello
I have the same issue with my own Telegram login. I tried on your website and the behavior is the same. Do you have any statistics that for you it works? Or can you check your website that it works?
I tried Safari and Chrome and Chrome in incognito (even changed the settings to allow third-party cookies).
However, Firefox worked for me.
My guess would be that it is somehow related to third-party cookies. They are blocked by default in incognito which breaks the Telegram Login behavior

same issue here

solved the problem by enabling third party cookies in safari.
here is a helpful article about it
