finishing: pull: generic error

I have this error when synchronizing files between two linux computer. Syncthing retrieved correctly some files in the computer B but stops with no error except this one.

2024-10-26 19:51:06 Puller (folder "all" (jkgkh-eexgx), item ".../000015.alto"): syncing: finishing: pull: generic error
2024-10-26 19:51:06 Puller (folder "all" (jkgkh-eexgx), item "/...000014.alto"): syncing: finishing: pull: generic error
2024-10-26 19:51:06 "all" (jkgkh-eexgx): Failed to sync 1130 items
2024-10-26 19:51:06 Folder "all" (jkgkh-eexgx) isn't making sync progress - retrying in 4m9s.

I did not set a password to sync share folder (Failed Items:syncing finishing pull:generic error)

I restarted syncthing in the computer B. I have no access to the computer A (sender) in this moment.

What can I do?

Assuming that the folder type is not “Receive Encrypted”, please make sure that there is no password set for the folder on either side. See https://github.com/syncthing/syncthing/issues/9784 for more details.
