Access voilation.
Capture packets and find that the IMC server responded with an error packet, causing the TFTP transfer to fail.
From the error Access violation, it is generally related to permissions, path restrictions, or security policies.
1. Acknowledge that the firewall and SELinux are closed.
2. Open iMC/server/conf/qvdm.conf and find that the TFTPRootDir path does not match the actual iMC installation path, causing the TFTP transfer to fail (file directory not found).
Solution
Change the iMC path involved in iMC/server/conf/qvdm.conf to the actual one, then restart the entire IMC to restore recovery
