Filezilla FTP not working with Jio Fiber connection

Hi all

Need some help, recently shifted from Airtel to Jio Fiber some time back. Surprisingly started getting and error while connecting to FTP sites using Filezilla on the jio network, however the same work fine when I'm connected to my airtel network

It starts with getting an error that the site does not support TLS and data will be sent in the open (works fine on Airtel, its an ftps site). Then it fails to connect to server since a secure connection is required.

I've tried putting rules in the firewall to allow filezilla access, have added a rule to give it access to port 20 & 21. Nothing works till now

Please help

Have you tried contacting Jio support about this? Could be that they block access to port 21 by default.

Have dropped them a line, still waiting for a response. Figured out how to get to the router settings, but can't find anything related to FTP or port blocking there

I doubt router settings will help you if they disable port forwarding in their own systems. I have the same problem with Tata Sky Broadband. I can expose ports in the router but I cannot see my services from sites like canyouseeme.org.

The jio care team finally replied back saying that the router does not support blocking or unblocking of ports. What now


BTW have asked them if they can help figure out the issue, but don't have high hopes

as per my personal experience, most of the people who respond usually to customers are idiots not knowing almost anything except simple copy-paste. this includes second level as well. third level or above may have some useful info.
imho it wold be better to write a detailed email asking someone from tech team to respond or ask for an engineer visit.

Download WireShark Wireshark · Go Deep. Capture and study the packets going to & fro when you initiate connection to your FTP site.

Check what protocols are in use, what are outbound ports, what are inbound ports, if data is received or not and so on. That might give you some idea what’s really happening under the hood.
Do the same with if you still have Airtel connection or with your mobile hotspot-based WiFi interface and compare the two.
There might be some learning curve though if you are not familiar with that tool!

There's no need to forward any ports in your router, unless you are expected to receive any explicit inbound connection, which does not seem to be the case here. Disable all firewalls in Windows as well as router if any.
