unity editor update check - connection to the update server failed

Question

I just install unity from the unity official site , and I want to watch my unity version , so I went to help->check for updates , but then I found a mistake , I can't access update server, I didn't watch my unity version , I watched it's connection to the update server failed .why? I already tried to completely uninstall unity , and then reinstall it , but it didn't work , I use the free version . I can access the asset store . I noticed I 'm using proxy server to surf in internet , so I tried to add System Variable , HTTP_proxy , HTTPS_proxy , make sure unity can also use the proxy , but problem is still here , nothing change.

Same here. I've had this problem for a while. Currently failing with: Unity 2018.1.5f1.

Other users mentioned that this used to be a recurring problem in Asia. I'm in Europe and I've also tried to VPN into another region, to no avail.

The last time I updated by downloading and running the installer.

UPDATE: this seems to be caused by an expired TLS certificate: https://issuetracker.unity3d.com/issues/connection-to-the-update-server-failed-error-appears-when-trying-to-update-unity-editor-via-check-for-updates-in-the-main-menu

hi , guys ,My problem already solved when I used the new version.

I think the new version may have not the problem , but I also do another thing , let me talk , previously , I use shadowsocks+ssr ,so I download proxifier to achieve real global internet access ,then I open unity , I found unity can access the update server ,though it say my version is the latest version , and I also found a error because of proxifier , so I uninstall proxifier , then I reopen unity ,error is gone and I also can access the update server , but I can't sure the update server is real work because I use the latest , until today I get this message . so I hope you guys can use the new version to solve the problem , If not , you can try to use proxifier , if you get error , just uninstall it , may be your unity can work like mine
