Upgraded to 2018.3 and lost internet connection, can't load Kotlin plugin
Answered
Just updated to 2018.3 and now internet connection seems down in IntelliJ only. For example, I can't get to the plugin's marketplace; however the browsers on the same machine work fine.
I doubled checked the auto-proxy settings by comparing to the browser settings and they are unchanged. I restarted IntelliJ several times, no change.
I can compile and run java source, but the Kotlin plugin is absent, no markup on the ".ks" source files.
Thanks for any help in this regard

I was able to transfer the InteliJ binaries 2018.2.6 from another computer not yet upgraded back to this one and it works. Can run Kotlin as before. I can get successful connection under Settings/System Settings/ HTTP Proxy/Check connection.
Lesson learned... don't delete the old version.
Doesn't solve the problem of how to upgrade in the future.
Hello,
Wasn't proxy settings imported into new version during updating?
For both 2018.2.6 and 2018.3 the auto-import proxy settings are correct. Yes this proxy setting was imported into 2018.3 when updating.
For 2018.2.6 I can successfully run the <Check connection> . For 2018.3 it says "Problem with connection". I'm also not able to get to plugins marketplace in order to load Kotlin plugin or any others.
If it is any clue, for 2018.2.6 I'm constantly approving certificates, but it works in between these approvals. I'm wondering if 2018.3 just stops if the certificates are not valid. That is, 2018.3 perhaps does not give the user the option to validate the certificate manually. I'm willing to try some experiments if you have ideas.
Could you please check if 2018.3 works fine with the manual proxy configuration with host/port/login/password?
I just tried entering the manual proxy configuration based on your suggestion. Version 2018.3 is working for me now, I get a connection, I could update the Kotlin plugin and then run a Kotlin main function.
Thanks, issue is closed for me.
Thanks for information!
