@mekkablue and @composerjk, the problem appeared before I installed the Murus Lite app therefore it does not depend on it. However, I will uninstall it.
@GeorgSeifert, I tried with adding this DNS and with deleting all others DNS but it does not fix the issue.
Will continue to search for solutions though.
If you’re comfortable with the command line, then troubleshooting with ping(8) and traceroute(8) could potentially help diagnose where the problem might be. I’m able to connect okay from here. Another thing to try is from a different network, in case there’s something blocking connection at that location. On your computer side, checking for proxy configs (in System Preferences > Network > Advanced for the network interface you’re using) or firewall configs (also in System Preferences > Security). Another check to try is from a different computer on the same network (a phone would count if on the same network, but could also be used to checking from another network, if turning off wifi).
Good luck.
Hi composerijk!
At the Network Utility troubleshooting with ping gave me this result:

The network is not the reason, as my laptop gets the same result everywhere. Other devices on the same network get access to this website and start downloading the app.
I tried to clear my web browsing cache; tried to leave checked and later unchecked the Proxies’ marks [e.g. once Auto Proxy Detect; later only Web Proxy (HTTP) and Secure Web Proxy (HTTPS) ]; disabled my Firewall;
Reset my IP Address and cleared my DNS cache typing into the Terminal:
sudo killall -HUP mDNSResponder
and later:
sudo killall -HUP mDNSResponder && echo macOS DNS Cache Reset
Despite all these attempts my outcome is similar: ERR_CONNECTION_REFUSED
Oddly, if I check if the website is down only for me or everyone it gives me this result even though from other devices works fine.
there is not actual page on https://updates.glyphsapp.com. So that response is to be accepted.
What happens if you open this page in your browser: https://updates.glyphsapp.com/Glyphs2.6.1-1225.html
I have the same problem.
I receive this message every time I click on “Review for Updates”:
There has been an error in data retrieval. please try again later
Hi Ebrahim,
I’m the one taking care of the Glyphs website. Maybe you (or/and others with the same issue) can help me find the problem.
If you know how to use the Command Line/Terminal.app, could you try the following commands and post the output to this thread:
ping updates.glyphsapp.com
curl -I https://updates.glyphsapp.com/latest2.php
dig updates.glyphsapp.com
Thanks!
https://glyphsapp.com does not open in my browser. By activating the VPN, I open it.
In my country some sites are blocked by filtering, but it’s unlikely that your site has been filtered!
https://updates.glyphsapp.com/Glyphs2.6.1-1225.html does not open in my browser. Even with vpn
ping updates.glyphsapp.com (vpn has been enabled)

Um, 127.0.0.1 is localhost, meaning the computer you’re running the ping command on. So, it sounds like there’s something overriding the normal DNS lookup for updates.glyphsapp.com on your mac or the other end of the vpn, or a DNS resolver.

May I have run an application that has blocked my access to this address?
How can I find it?
https://updates.glyphsapp.com Opens on my Windows Pc and Android mobile (that are all connected to same network.)
The dig DNS results look correct, though. That 172.104.142.40 address is what one expects for updates.glyphsapp.com right now. That’s what I’d have expected to see instead of 127.0.0.1 in your ping command run.
Sometimes ad/tracking blockers will have those kind of DNS override mappings to localhost.
Did you ever install something like MacKeeper, antivirus tools or system optimizers? Get rid of them, please. They are not needed on a Mac and are known to cause more trouble than they solve.
Maybe the VPN software is interfering?
Can you try to use 1.1.1.1 as your DNS server?
I do not use ad / tracking blocker app or extension!
I installed the CleanMyMac app. But the problem was not solved by uninstalling it.
I used 1.1.1.1 as a DNS server, used different browsers, used a different VPN, but failed 
I am now confident that there is something on the Mac that prevents connection to your server. But I do not know how to find it
The solution is to reset your hosts file
Do it as explained in this tutorial, scroll down to How to reset your Mac’s Hosts file
feedback your result.
That is an interesting idea. Can you send us the ‘hosts’ file?
