Why does my Bitcoin daemon take so long to synchronize?

Looks like you were close to the tip, and a peer didn’t send you the requested block 000000000000000000022d579c5f43eace7948f5e2fd86b34345a0f482268545. This looks similar to #29281 and would be fixed by the open PR #29664.

So what should I do now?

you could just restart the node and see whether the problem persists. If it’s the problem I mentioned above, you should connect to new peers and the problem should go away. If it persists, it’s probably another problem, e.g. networking issues.

When using the 32 bit version there was no such problem with synchronization. Internet seems to be ok. Restarting bitcoind doesn’t help.

Can you clarify this. Does the debug log look the same after the restart?

Closing for now, due to lack of details, but please leave a comment if you get a chance.
