The Algorand Foundation urged node operators to upgrade to v5.0.3 after a DNSSEC validation issue prevented some nodes from joining the network.

DNSSEC, a system used to verify that internet domain information has not been altered, is involved in the startup problem. The issue can prevent nodes from joining the network when they are started or restarted.

Version v5.0.3 fixes the DNSSEC validation problem.
