I already suggested that method - further up …
Doesn’t work either, it seems.
I thought he was set on doing it via curl for some reason.
Now I’m pretty sure it’s not OpenSSL or GnuTLS that’s buggy here. The fact that others could access the server find (me included) implies that there may be some network equipment on the way from your computer to the server that might be causing this.
Can you run openssl s_client -host upwork-usw2-desktopapp.upwork.com -port 443 -debug -msg?
I do not know anything about networking, im just a developer.
So when you talk about faulty networking equipment u’ll have to tell me wheather you’re talking about my Router or my ISP.

It’s hard to say, could be either.
This is odd, as in my case, I get
read from 0x55c1921c3700 [0x55c1921d9303] (5 bytes => 5 (0x5))
Note the difference. The read on your side returns 0, while on my side it returns 5. 0 indicates the end of the connection. It seems for some reason the TCP connection is being terminated.
Please start sudo tcpdump port 443 in one terminal, then very quickly after that run curl https://upwork-usw2-desktopapp.upwork.com/webapp/scripts/main.js > /dev/null in a different terminal, after curl has stopped, go back to the first one, and stop tcpdump by pressing control+c.

Looks like you’re blocked and the server doesn’t want to talk to you.
@moson why would upwork block me. And i’m not using a static IP.
@pobrn Not sure if i’ve captured the right packets:

After the first 517 bytes of data sent from you, the server initiates a connection termination for some reason.
I do not understand were u’re going with this.
i’ve just installed this OS, and i do not know much about networking
Don’t ask me. 
Maybe the IP-Address that you’ve got right now has been used by someone doing nasty stuff before.
Did you try to reboot your router or reconnect (to force an IP-Address change) and then try again?
Try TOR browser or VPN or a proxy and see if things are different then…
@moson
i can log-in on upwork without any VPN, the only problem that i face is using their Desktop App.
What I meant is to try via a VPN or anything (or try going via mobile phone (tethering)) that does effectively change your IP address just to find out if it is your IP-Address that is currently blocked on their side…
First thing i would try is to restart / reconnect the router to force an address change (note down your external IP address before and after to be sure it changed).
I have a dual boot (Windows & Manjaro), both have upwork desktop client.
Window can access the desktop client without any problem.
But Manjaro cannot not.
Which prove that upwork did not block me.
And even my phone has upwork (Android) and it is connected to the same Router…
So i really don’t want to believe UpWork has blocked me. 
Edit
If Upwork wanted me out of their platform, they would closed my account. 
And i even spoke to them about this issue, they told me everything is fine on their side, the issue is on my side.
That is all really strange indeed.
And it is info that “we” didn’t have.
You where on Ubuntu, you said.
And have had … similar problems there.
One perhaps interesting thing to try and see the result of -
to me, anyway, if I where you -
would be to boot the installation medium of Manjaro
and try that curl and wget command there
and - if you still have it around
do the same with an Ubuntu or other live linux medium
just to see whether there is a difference in behaviour
between your now actual installation
and … the other, not as current, flavours of linux
Ok, good. At least you can sort that one out now.
Back to the issue:
What I find weird is the addresses that are resolved on your end for upwork-usw2-desktopapp.upwork.com
On my end this is:
upwork-usw2-desktopapp.upwork.com. 300 IN A 104.18.89.237
upwork-usw2-desktopapp.upwork.com. 300 IN A 104.18.90.237
On your end it seems to be “146.112.252.240”.
And that one seems to belong to “OPENDNS”:
role: OPENDNS NETENG TEAM
address: OpenDNS
address: 675 West Hastings Street, Suite 500
address: Vancouver BC V6B 1N2
address: Canada
Something is odd.
Please post dig upwork-usw2-desktopapp.upwork.com
@moson Sorry for the late response.
