Am I the only one with this issue?

What? You mean you didn't have to flip switches to load the registers first to move the paper tape to move the mag tapes and then get an IPL going? whew... old memories...

One of my sons is still living in the VM green screen world from time-to-time for banking systems (the ones behind the scenes or should I say behind the GUIs). He says not many people want to do it and I tell him it's a good skill to keep.

LOL... back then, I thought when the removable disk packs came out that was COOL!

Of course the operators were happy when they came out with the 8" floppies and they no longer had to trim back the edges of tape reels so that they could feed them thru the tape drives.

Those where the days my friend, (at times) I thought they would never end..... so now all of us DP/IT folks are blind from CRTs.... but, we certainly were well paid!

LOL!

Ok, time to nerd out and I hope someone can assist.

My setup. Laptop running two VMs. One is my development environment, the other is an Oracle database. The development environment uses a VPN to connect to Linode servers that contains our ticketing system, test Oracle database, etc.

Now for the issue. I have my phone as a hotspot carrier doesn't matter, it is a hotspot. I can ping, ssh and sftp the servers. But I cannot browse to them. Get more nerdy here I can "curl" to the http side but I get no response if I do the https side.

It looks like a hotspot is out of the question or I am missing something. Congratulations if you made it to the end. I am hoping there are other nerds like me out there.

Thought: Are you ssh/sftp/curl via domain name or IP? Can you browse to your server by IP, starting to point at DNS issues?

It has to be the port that is getting blocked. This is a phone hotspot so it is not that robust. Because I can do everything (ssh, sftp, etc) i just can't do https

I do this quite often on my iPhone 12 Pro serving a hotspot to my tplink travel router. Or directly to my Mac. It works fine for both. Has to be something with your phone or cellular provider I would think. AT&T is my provider.

It's not his provider. He was using T-Mobile and Verizon. I have both and have never had any issue.

Agree - white/black port/IP lists on the server or whatever firewall(s) is/are in front. Set by policy. Kept thousands from getting to AWS workspaces until they moved into a commercial building with commercial connectivity.

Despite the number one priority program, took over a YEAR to resolve.

Agreed. Something on one end of the tunnel or the other is blocking this. It's not the provider. They can't discern SSH from HTTPS from RDP if a VPN is in use.

OP, have you considered an LTE or 5G router? Those can be made to work on most networks by monkeying with the IMEI. Not permitted by the ToU but I know a guy (not me, seriously) who does this for his van and it works great.

Agree. Check the hotspot firewall is culprit. See if you can turn it off and test, then figure out which ports are being blocked.

I have a very similar setup, laptop with VM for dev environment. All of our infrastructure is hosted and the database is restricted to trusted IP access. I found that Hotspot access (phone or actual Hotspot device does not matter) uses a sort of rolling IP address assignment. This is turn makes getting your devices ( phone, laptop or VMs) true IP address more challenging because windows commands like ipconfig and websites like https://whatismyipaddress.com/ do not tell you the IP address that represents your device.

Here's what I found, run this command from either a command prompt or PowerShell as administrator. Register this IP address as your trusted/whitelisted IP address. This has to be done every time you connect to the Hotspot.

Not sure if this is your issue but thought it would be worth sharing since I spent several days figuring this out.
