thanks for your quick response. The URL requested is provided by the Sentinel-Hub plugin.
I had already checked the blog entry you quoted, but the QGIS and plugin versions are obsolete, the configuration dialog is completetly different so I cannot follow the instructions. I am using QGIS 3.4, Sentinel Hub plugin 2.0.
I checked the webinar and the plugin is setup as I mentioned.
But I have discovered that it is a network/proxy issue: My company uses a web proxy to access internet. That’s why I cannot connect from the sentinel hub plugin.
I made a test: changed the network connection to shared wifi from my cellphone (no proxy) and the plugin logon successfully. Unfortunately, I need to work from the company network, so I cannot bypass the problem.
So now the question is what URLs/ports need to be open in order to connect to the sentinel-hub services from the plugin?
I’m afraid the sentinel plugin is stuck in the login process, before any data is requested. The question is how can the login be completed? Perhaps the plugin is trying to access an Oauth server which my proxy is blocking?
thanks for the reply. I may be wrong but including [services.sentinel-hub.com] is not enough as long as the login process connects to an AWS server not included. Is there any “core” domain for the plugin or maybe an IP range we can include in the white-list? Otherwise the Oauth packets will be blocked in our proxy and the login will not complete.
Shall I post a separate topic for the login issue?
Thanks again for your patience. I have noticed that the port 443 is not reachable on [services.sentinel-hub.com] from the corporate network. I have reported the issue to IT support and hopefully that will solve my problem.
