Latest version incorrectly detects proxy and fails to connect

[michaelctaylor]

One of your programmers appears to have broken the desktop version of Spotify as of this week - where is the QA on these projects?!

Problem:

I was presented with a situation this morning where Spotify desktop was displaying the cannot connect error due to network related issues - false.

Spotify desktop now incorrectly detects a completely "full transparent" web content scanning feature within the Sophos/Astaro UTM firewall.

** THIS FEATURE WAS WORKING for years up until the latest update where Spotify is now coming to a HARD STOP because it fails to understand what a fully transparent proxy with URL filtering ONLY actually is and how it works.

There are no settings to be manipulated by the user, nor the adim - I AM the admin BTW and there is NO username and password to be used with fully transparent proxy.

Entering any proxy setting still fails with the desktop application - as expected.

What I have done to ATTEMPT to fix:

-Uninstalled and reinstalled Spotify on multiple computers - followed all Spotify guides.

-Observed firewall web logs - no blocking actions for affected computers attempting to access Spotify or their servers.

-Logged into the web play on the same computers and everything works as expected - NO ISSUES.

Possible cause:

-I believe that Spotify is detecting a self-signed certificate that is used by the firewall and immediately failing because it believes that the traffic is being proxied in a manner that will cause Spotify to fail - NOT ACCURATE.

-This is a false assumption because in the scenario, all port 80 and 443 traffic will be transparently proxied, as all web traffic is being proxied but uninterrupted unless the URL is a positive match for something nefarious.

-There is no need for a client side certificate, nor credentials as evidenced by the ability to play Spotify via the web player - NO ISSUES.

Again, the web player works correctly.

My request:

-Change the firewall detection methods back to what they were within Spotify prior to this latest update - it was working correctly.

-STOP forcing Spotify to automatically update itself every time that it is executed this is overboard and causes so many issues and troubleshooting man-hours on the users' end.

-Paid users should not need to use the "community" to solve problems - poor customer support when I have to submit a request via the "chat" page and not a trouble ticketing system.

Tech info:

-Plan - Premium

-Spotify version: 1.1.27.472.gf6574b97 The average user would never locate this, you cannot access that info without logging in or you must know how to locate the versioning info within the install package - not helpful for most.

-Windows 10 Pro version: 10.0.17763

-Firewall: Sophos UTM version: 9.605-1 (Full transparent web filtering URL only).
