OPPM fails to install [HTTPS certificate not supported by old Java versions]

[HauberRBLX]

So yesterday while playing around with a modpack, I discovered OpenComputers. Today I installed the mod on a seperate modpack I made for testing OpenComputers, the OS install went well, however when I tried to install OPPM, it told me that it couldnt connect to the internet. After reconnecting my WiFi, using a VPN and using my mobile hotspot, the issue persisted. I have also checked and the computer is configured correctly. It has an internet card and any other components it may need.

I am on Minecraft 1.7.10 with OpenComputers version 1.8.3+089dd28 and Forge 10.13.4.1614 installed.

The log file can be viewed here: https://pastebin.com/DFq4FJWm

I suspect it has something to do with the Java version being outdated:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

@asiekierka I am running Java 1.8.0_261. I don't think that's the issue.

Here's what it shows me when I run java -version:
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)

Enabling ArchaicFix's enableLetsEncryptRoot feature might have a positive effect?

ArchaicFix crashes the game if I try to run Minecraft with it

So what do I do?

Replace the Java 8 version with the latest version. For example, turn off "Use Java provided by Minecraft" in ATLauncher
After testing, there are no problems

I'm using the CurseForge Launcher. Is there any way to do that on there?

Sorry, I haven't used this before. Why don't you search it on Google?

@HauberRBLX You'd need to manually change the Java version after CurseForge launches the vanilla launcher -> Installation Tab -> Edit the modded profile -> MORE OPTIONS -> edit JAVA EXECUTABLE.

@HauberRBLX An updated Java 8 executable.
