The team is actively investigating these reports. Apologies that I don't have more information beyond that.

We'll be using this thread to convey any progress, as well as additional requests that may aid the team in finding a fix. Thanks!
(merging related threads as they come)

For those experiencing the connectivity issue, could you please attempt the following:

1. Go to "Manage game and add-ons"
2. Select "Saved data"
3. Select "Reserved space" for Warframe and Clear Reserved Space

If this is something you've already tried please let me know!

Thank you to everyone for trying and reporting back!

Couple other things on the check list:

• Confirm that Warframe is fully up to date. You should see "Version 4.3.0.0"
  • check for an update under Manage game and add-ons.
    • if you click on "Updates" it would show an updated needed for Warframe
• Confirm if you're on IPv4 or IPv6
  • you can check this by going to your Network settings

Have version 4.3.0.0, no updates available. 

Which should it be on, IPv4, or IPv6?

It’s currently IPv4, not sure how one would go about changing that

IPv4 is good! Thank you for checking :) 

Are there others in this thread that're also using a VPN?
