There are a LOT more messages than that. Including messages which talk about restoring cached attributes.
Honestly, *read* the debug output. ALL OF IT. If there's nothing about the cache, then you didn't configure the cache properly.
I fail to understand why you're only looking at the final access accept. The REST of the debug output shows more information about previous actions, like caching...

Yes, if you *read* the debug outputs you'll see why. There's no "inner-tunnel" being run for the cached session.

TBH, first upgrade to the v3.0.x branch on GitHub. I'm pretty sure I already suggest this. That makes caching easier to configure. See the "cache" section of mods-available/eap in the v3.0.x source.
Then, READ the debug output. ALL OF IT. Do simple things like LOOK FOR THE WORD "cache" or "caching".
The more you ignore the debug output, the harder it will be for you to understand the problem and fix it.
