'The modpack The 1.12.2 Pack does not appear to be installed or is corrupt, and is not available for Offline Play.'

[AshPilot]

I have gone in to my firewall and allowed everything Java related access.
Tried running in Admin mode.
Uninstalled and reinstalled Technic launcher and completely deleted the modpack 1.12.2 from the .technic folder in %appdata% etc.

Shortly after the issue started I updated to the most recent version of Java.

I cannot download the modpack; at the top of the modpack page it says in a red bubble 'Offline' but only for this one modpack.

I have also tried adding the enviromental variable in advanced settings '-Djava.net.preferIPv4Stack=true' which had no effect.

When I try to download I get the following messages in the command prompt:

[Jakorosin]

I have the same issue with 1.12.2 and 1.7.10. One of the problems at play is that the Solder/Endermedia site's certificate has expired.
