Secure connections to computers from outside LAN are unstable
I have four computers in my apartment that I regularly connect to from outside my network. I forwarded the ports on my router, set up my asuscomm DNS, and everything worked well for months. Then, last week all four computers simultaneously stopped accepting remote desktop connections from outside my local network (inside the LAN everything works fine). RDP will log on for a second and then immediately quit. My plex server stopped playing remotely (unless I disable secure connections). Also, I cannot upload to dropbox. My feeling is that encrypted traffic connections are somehow unstable. The fact that it happened to all my computers at once makes me think its a problem with my router, modem, or ISP. I'm somewhat of a novice when it comes to networking so I could also be way off base.
What I've done to troubleshoot (with no success):
- power cycled everything
- rolled back windows updates to two week before the problem started
- followed guide that had me look for/delete a certificate file in the registry (it didn't exist in my system)
- replaced asus AC68u with asus AC88u
- replaced cable modem sb6183 with same model
- called ISP and asked them if there was any issue on their end (they said no)
- re-installed network driver
- various network resets/releases
Finally, when I was at work, I uploaded a file to my dropbox and it worked (as expected). When I brought the same laptop home and tried to upload the same file, it failed. When I brought the laptop back to work, it worked. This, along with my new router and modem exhibiting the same symptoms as the old ones makes me think it's an ISP problem.
I'm at a total loss.
