Hey @verynohair!

The logs indicates that the file is corrupted somehow. We have previously seen this occur sometimes when importing the snapshot directly into Lotus. From the logs it also seems like you did not specify path to the snapshot correctly (e.g /path/to/2325360_2022_11_10T08_00_00Z.car)? So it can seem like it tried to import the snapshot directly.

I suggest trying to specifying the path to the snapshot.car file. If not, try to download the snapshot again using aria2c.

Converting this into a discussion, so we can troubleshoot furter there if there are any more questions.
