IBD stalling issue in v26.0 and assumevalid=0 #29374

Is there an existing issue for this?

• I have searched the existing issues

Current behaviour

I'm using v26 with assumevalid=0 and the IBD keeps stalling after the log message says Potential stale tip detected, will try using extra outbound peer, it retries but same message keeps repeating unless I restart the software. I saw someone on bitcoin stack exchange suggested to not use VPN, I'm not using any VPN or tor. Just simple clearnet on a fresh Linux OS.

Expected behaviour

Ideally it shouldn't get stuck, it could be a painful experience to restart multiple times specially if it takes much longer with assumevalid=0.

Steps to reproduce

I'm not sure if it can be reproduced easily.

Relevant log output

Potential stale tip detected, will try using extra outbound peer

How did you obtain Bitcoin Core

Pre-built binaries

What version of Bitcoin Core are you using?

v26.0

Operating system and version

Fedora v39 Workstation Edition

Machine specifications

Machine specs: 11th Gen i5 x8, 20GB RAM, SSD nvme

bitcoin.conf :

Closed this issue for now, just realized that it seems to be an issue with internet connection going down on the machine. It could be unrelated to Bitcoin software so doesn't make sense to investigate further on this one.
