I need to run REST API on ASA (to be able to cooperate with script for lets encrypt certificate) - no problem with downloading the image and enabling it. Even with functions of the REST API self have no problems.
I encounter problems with running firepoware services on the same box. First I was unable to install firepower services - I tried it several times. Then I realized it was due to REST API enabled.
I had problems with uploading image to ASA flash - I was unable to format it - it called the disk is used by some other application - again the issue disappear once a disabled the REST API.
Last time when REST API was enabled for aprox 2 weeks I realized I cannot connect to firepower services - It lost configuration for connection to Firepower Management Center - when I setup it again, it calls another error it cannot establish the tunnel - so the whole configuration of the firepower services was somehow corrupted. I had to reimage the firepower services from scratch.
It seems to me the REST API somehow impacts access to local flash and this caused the issues I encounter.
Has anybody else similar problems with running ASA REST API?
