Only first import to my local node is found by gateways

Imports to local IPFS Desktop work. My Firefox uses IPFS Companion and can find them all. But only the first import ( 1 week ago ) is also found by ipfs.dweb.link . The others get 504 Gateway timeout. IPFS Desktop is online since 9 hours.

Please help. Thanks!

Probably a reprovide issue. When you import a file, it is immediately provided to the DHT. Those records will expire after 48 hours. If your node is running continuously, it will start a reprovide run after 22 hours (the run may take a long time, depending on how many blocks you have and what your configuration is). If you shut down your node and let the records fade, your files can no longer be found. Once you restart your node, it may take up to 22 hours before it starts reproviding. Your files remain inaccessible until their records have been reprovided.

Also, while your node is down, your files are inaccessible, even if the records still exist in the DHT.

In short, don’t shut down your node, OR use a repinning service that will serve your files while your node is inactive.
