Tobias,
Makes sense, but just to understand what is going on and know how
to read the logs, are you saying that each "ESP:" prefix signifies a
separate proposal that is parsed independently (log below)? A single
proposal might have one or more algorithms separated by slashes, correct ?
Thanks,
Jafar

Hi,
I see an error in the strongswan
logs and I'm not sure what is going on here, and what I should do to
correct this:
There is nothing to correct as the connection gets successfully
established. If you have a closer look at the log you see that the
client sends not one, but four ESP proposals. The first one contains
only AEAD algorithms (AES-GCM etc.), which won't match your configured
proposal, hence, the "no acceptable ENCRYPTION_ALGORITHM found" message.
Then the second proposal is tried and that matches your configured
proposal and is selected.

Tobias
