Curl Error (35) SSL connect error / Curl Error (56) Failure when receiving data from the peer

[Bumsteer]

Howdy,
I am getting this error repeatedly when trying to update DCS to the latest version. I dont think it is a firewall issue as I have been downloading updates for many months successfully, but who knows. Any help greatly appreciated.

I have the same problem too while using dcs_updater.exe

and got authorization failed 503 (error 35: SSL connect error) while try open game in steam. https://forums.eagle.ru/topic/256969-request-dcssettings-failed-with-error-60-ssl-peer-certificate-or-ssh-remote-key-was-not-ok/

This happens when something intercepts HTTPS connections. Either your ISP or some software (malware?) on your computer.

Thanks guy, I check several times there are no malware (no antivirus, no firewall) in my PC, and when I turned VPN on, I can browse the www.digitalcombatsimulator.com in browser, but got SSL error through the DCS_updater.exe.

And can you browse the site w/o VPN?

Yes

@Bumsteer@stealthmanHave you solved this issue or are you still stuck?

[Antoha]

All the same, how to solve this problem?

[Flappie]

Hi @Antoha. So far, no DCS user has provided a solution. c0ff suggested this could be caused by an external software (firewall, VPN, malware). I've found this article giving some hints.

 

Quote

1 – incorrect computer time and date is most reason for SSL connection error.

2 – Jumbled SSL testament name with the area name

3 – Untrusted, obsolete or unapproved SSL endorsement

4 – firewell and antivirus protection in pc most factor for SSL connection error.

5 – Site page containing some uncertain information

6 – Program issue (browser problem)

 

Ensure Windows time synchronization is acivated, and that the timezone is OK. If it's not, try this.

[Antoha]

Thanks for the hint. So far, nothing helped. The developers are silent (((

Thanks for the log. It might not just be an SSL issue after all. You first get a "timeout was reached" error.

Let's assume DCS cannot reach the internet at all. What are your antivirus and firewall apps?

Have you tried setting them off before launching DCS yet?

[Antoha]

The problem was solved after restarting the router.I think there is a problem with the internet service company.

Even after that, we managed to update the DCS from the second time

[Antoha]

Oddly enough, other apps and games worked stably.

If I understand correctly, you can now update DCS, but always after failing once?

Hate to necromance this thread, but I'm getting this error now too. I've rebooted my router/modem, I've turned off my firewalls, and antivirus, I deleted all files including installer and tried a fresh install, some times it gets to around 1,975mbs downloaded then throws up this error, some times it doesn't make it as far. I'm a new user, but I would love to try to play. It starts out at a slow 5mbps download speed (I'm on a 500mbps connection) then drops completely out before throwing this error up. As well as error 52.

Hi! I've got a problem with DCS installation: Curl(35) error: SSL connection error. It firstly appeared when I tried to update DCS. I decided to remove DCS from my computer and reinstall it, but, unsurprisingly, this didn't help. Actually, I've already turned off Windows Defender and checked Wi-Fi router, but error still dislays. Help, please, if it's possible.

Have you tried rebooting your router yet?

Yes, and I've already turned off firewall on it. Also I tried to use Internet from mobile phone, but all is the same. So, I suppose that it's not a problem with the router.

[Flappie]

After I sent my previous post, I saw my PC had trouble connecting to DCS servers. Is it any better for you today?

[Leo-yorsh]

Just an hour ago I tried to install DCS, and it returned this.

Mine was a hard drive issue. Replaced that and it works fine now

[Flappie]

Thanks.

@Leo-yorsh Can you please run the following command in a CMD window to try and fix your drive?

sfc /scannow
