I've only just recently had issues accessing quite literally every Spotify service apart from the Web Player. This includes the website, the Desktop App Download Site, the Desktop app itself, and the Android App. The Desktop App and Android App tell me I'm offline even though I'm connected to fully working internet and don't have offline mode enabled. I've reset my router multiple times, and made sure Spotify is enabled in my firewall.
I can't access Spotify's main website to view my account or redownload the Desktop App, as it just goes to the "Problem loading page: Connection has timed out screen". This is with fully working internet and access to multiple other sites, i.e. Youtube, Google, Facebook. etc... For some reason I can access the Community Site and the Web Player, and my account and playback works without any issues on the Web Player.
If I switch from Wifi to Cellular Data on my phone, Oppo A73, Spotify works with no issue. It connects and lets me playback fine. Only when I switch back to Wifi does it stop working again.
My account's email is *snip*
