Can't join any servers

Tried a friends server and three Keen (#1, #3, and #6 I think) servers. What happens is always the same: "Waiting for server to respond" then about 40 seconds later "Server not responding." I attached a log of attempting to connect to Keen NA #1.

Facts:

#1: I have no mods enabled.

#2: The servers I try to join have no mods enabled.

#3: My router has UPNP enabled.

#4: No problems with any games other than Space Engineers.

#5: Cleared AppData\Roaming\SpaceEngineers and it didn't change it.

#6: I confirmed Windows Defender Firewall Inbound rules were present and I replaced them with a more permissive rule ("any" profile and "any" protocol). I've also added an equally permissive rule to Outbound.

#7: I have no mods enabled.

#8: Judging by my computer's and the routers network activity performance counters, it appears there is little to no network activity when it says "Waiting for server to respond."

#9: I have no problem running Space Engineers other than the other ticket I just submitted (results in sporadic dropping to the main menu).

#10: I ran a dedicated server on my machine and connected to it via LAN without problems but no one could join it.

#11: No one can join my "Friends" games.

#12: I verified files in Steam.

#13: I have the first three DLCs but not the three new DLCs.
