[ERROR] invalid restore file (end)

[hndrbrm]

I use hydra with this script:
./hydra -V -l admin -x 1:6:a1 192.168.10.19 ftp
Then press keyboard Ctrl-C.
When try to resume its error:
[ERROR] invalid restore file (end)

I have read the similar issue, but i think its different.

When i use the debug it stop in the last step (step 12).

frogit@frogserver:~/thc-hydra$ ./hydra -d -R
Hydra v9.6dev (c) 2023 by van Hauser/THC & David Maciejak - Please do not use in military or secret service organizations, or for illegal purposes (this is non-binding, these *** ignore laws and ethics anyway).

I use hydra from the git (build it manually) in ubuntu server.

Heres the restore file.
hydra.restore.zip

My guess theres bug when parsing the restore file, such that the ending position is not on the ending of the restore file ('Hydra' token).

Note:
Previously i have use dictionary file, and the restore is working fine. This issue happened only if i use the -x options.
Are there any tool to simply generate the -x into txt file? So i could simply use the dictionary one.

I'm facing a similar issue. I've set up three Hydra sessions targeting different SSH ports, and I've stored their data in distinct folders to prevent any conflicts with hydra.restore. However, when I try to restore one of these sessions, it fails with the error message '[ERROR] invalid restore file (end)'.

:This error seems to occur consistently whenever Hydra runs for an extended period.
