vladi Are there any logs on the mount?
I don't believe there are log files in the mount, but if you had gathered your frames using the ASIAIR AutoRun, then the PHD2 logs should still be in your storage (it is not erased when you erase the AutoRun files).
Use a computer to log into the Samba server of the ASIAIR. On macOS, just use the Finder's Go menu (in Finder's main menu bar), select Connect to server from the Go menu, and give it an address of the form smb://aaa.bb.c.ddd, where aaa.bb.c.ddd is the IP address of the ASIAIR (which you can find from the ASAIR Settings window of the ASIAIR app, or from your router). If the ASIAIR is connected using Station mode, or directly with Ethernet to the router, you can also click on the Browse button, and the Mac will find the ASIAIR as a network server.
Once the server is opened, log in as Guest (no password), and you will be asked for the volume to open. If you are using the microSD card for storage, select the volume "TF Images." If you are using USB storage, select the volume "Udisk Images."
When the volume is opened, you should see a folder named "ASIAIR," with a subfolder named "log". In the log folder, you should find both AutoRun logs and PHD2 guide logs that have dates as part of their names (the PHD2 logs can be inspected with the PHD2 tools; they are just ASCII text files). Note that the date and time in the file names are UTC, but the server's file dates are local time :-).
