Could not send request, Error: Request timed out

Hi Team,
I am new to postman, trying to access a webservice but getting below error.

“Error: connect ETIMEDOUT 1XX.X7.1XX.XXX:4XX”

I tried modifying the setups after checking this forum, but none of the combination worked. As the same link is accessible for my other team i believe something is blocking request getting sent from my system. Kindly help me resolve this issue

Thanks in adavance
