Turn ZM debug up to about 3 to 5 and limit the output to zmc and check the resulting debug logs for what is actually happening.
The possibilities are failed authentication, bad path, unsupported format, incorrect image size configured, etc. etc.
Hi cordel,
many thanks for info. I have tried these debug settings and here is log file:
