I have JioFiber connection from previous 1 year. It was smooth until today when I suddenly started facing issues in my work. Due to WFH, I need to connect to Microsoft Azure cloud DBs very often and use them during software development. It was shocking to me this morning when I was unable to connect to Azure DB from my laptop. I used it on JioFiber last time on Friday night.
Initially, I ignored the issue thinking it is at the MS, but later to my surprise my colleagues on other networks were able to connect.
I started experimenting, switched to my Jio Mobile Data hotspot, and the problem was not resolved. But when I switched to Vodafone mobile data hotspot, I was able to connect to Azure DBs.
This made me clear that the problem is with Jio, maybe their firewall is blocking the port or so.
Even though I have raised a ticket with Jio, I don't trust them that they will resolve it.
Wanted to ask in this forum if anyone faced such issues earlier with Jio? if Yes, how you resolved it?

PS:
Azure DB URL: ****.database.windows.net:1433
**** = my work DB which I can't disclose.
 
Have you also inspected this with wireshark or any other tool to capture packets? What does it do when you try to establish a connection to a destination on port 1433?
 
@ishanjain28 nope, I'm not allowed to use these tools on my office laptop, and my personal laptop is not with me right now.
But i tried to check using curl commands..
I executed curl portquiz.net:1433 --connect-timeout 60
This command gives connection refused error..
Where as same command with port 80 work and gives success message.
 
@shashankb I'm unable to find the contact of nodal officer. Can you share the details if you have it handy ?
Btw this is not only with JioFiber but Jio4G too facing this issue. Hence I may need to complaint to both nodal officers.
