Here is the proof with CatchupBlockDownloadRetryAttempts set to 20000 on the mainnet:

pi@raspberrypi:~/node $ ./goal node status -d data/ -w 1000  
Last committed block: 4058  
Sync Time: 7118.6s  
Catchpoint: 11070000#Z5GVD2WLQ2MIG37UJPGPMA2JG7EWAFEDJKHBXAAOWP63ABV553TA  
Catchpoint total accounts: 7593802  
Catchpoint accounts processed: 7593802  
Catchpoint accounts verified: 0  
Genesis ID: mainnet-v1.0  
Genesis hash: wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=

it got stuck like that and meanwhile the sync time continued:

pi@raspberrypi:~/node $ ./goal node status -d data/ -w 1000  
Last committed block: 4058  
Sync Time: 7702.6s  
Catchpoint: 11070000#Z5GVD2WLQ2MIG37UJPGPMA2JG7EWAFEDJKHBXAAOWP63ABV553TA
