Strange reports of Scalar not working in incognito browsers

[turt2live]

Not sure how much we need to investigate this, but if it comes up again then there's at least an issue to track it. Conversation starts at https://matrix.to/#/!iNmaIQExDMeqdITdHH:matrix.org/$1550683243135lBoFX:targodan.de?via=matrix.org&via=linuxgaming.life&via=disroot.org

Summary:

• My HS + Riot Desktop: works
• My HS + Self hosted Riot in Google Chrome (normal mode): works
• My HS + Self hosted Riot in Google Chrome (incognito mode): doesn't work

Working refers to being able to open the integrations panel. Doesn't work means I can't open it. In the console I was able to find this:

Failed to load resource: the server responded with a status of 500 ()
rageshake.js:99 Error whilst initialising scalarClient for ManageIntegsButton Object
e.(anonymous function) @ rageshake.js:99

The related call was to https://scalar.vector.im/api/register with the content {"expires_in":3600,"access_token":"REDACTED","matrix_server_name":"targodan.de","token_type":"Bearer"}.

This responded with a 500 and {"message":"Failed to authenticate user"}

Hi guys, I found the solution that your setting from firefox: tracker blocking. There 2 problem here:

1. Server name should be parent domain example.com not chat.example.com
2. Shoud not block tracker from Scala to appear sticker packs and integrations

I don't believe this is actionable in 2021/22 in its current state. If people are still seeing this, please open a new issue with more details.
