Check the `bisq.properties` file for the non-working Bisq instances. There’s a property named `bannedSeedNodes`. You probably have addressess that are not in the format: [ADDRESS]:[PORT]

You can try changing the format, or perhaps deleting the comma-separated list. I believe the problem stems from here: [bisq/DefaultSeedNodeRepository.java at v1.6.2 · bisq-network/bisq · GitHub](https://github.com/bisq-network/bisq/blob/v1.6.2/core/src/main/java/bisq/core/network/p2p/seed/DefaultSeedNodeRepository.java#L75)

The filter checks that the address string is not empty, but it does not check that it’s in the right format. So when the `NodeAddress` constructor is called the `checkArgument` fails, as shown here: [bisq/NodeAddress.java at v1.6.2 · bisq-network/bisq · GitHub](https://github.com/bisq-network/bisq/blob/v1.6.2/p2p/src/main/java/bisq/network/p2p/NodeAddress.java#L51)
