Hi Hamal,
Upon revisiting this issue, I believe the problem might be what I described here: Cannot link to Stellarium - #3 by sebagr
What I said there 2 years ago applied to Safari, but now it seems we have this issue on Chrome as well.
Unless the Remote Control plugin in Stellarium is upgraded to accept HTTPS connections instead of or additionally, I’m afraid there’s not much I can do from here
