Getting "The lobby server connection has encountered an error" number 2002, EU server

This started happening today. When trying to connect to Light or Chaos data centers (AKA the European ones), I get this screen:

No buttons, no characters, no nothing... And a few seconds later, I get the error in the post's title. I press OK, and FFXIV closes.

NA data centers work fine.

I tried restarting my router, restarting my PC, and turning off my antivirus and firewall; nothing helped.

Any advice?

EDIT: Just tried running FFXIV on my laptop, while connecting my Wifi to my sister's phone's Hotspot, instead of my actual internet. And lo and behold... It works.
So does that mean there's some sort of issue with my internet...? What can I do to fix it? :C

Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Please try the following troubleshooting steps:

- The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

For some reasons this error is something I'm getting repeatedly
worked just fine for 20+ days, new player here
I've tried with firewall bypassing - didn't help
I've tried restarting the router several times- didn't help
I've tried flushing DNS - didn't help
I've tried restarting pc - also with no avail

Is there anything more I can do or attempt to log and play?
