SELinux is preventing ecblp from 'open' accesses on the fifo_file /run/ecblp0.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ecblp should be allowed open access on the ecblp0 fifo_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'ecblp' --raw | audit2allow -M my-ecblp
# semodule -X 300 -i my-ecblp.pp
