I am deploying three nodes of indy-node deployed in 3 different machines, when I deploy them, they normally work fine and I can publish and get DIDs from the DLT doing something like:

indy>     pool create identity_pool gen_txn_file=/var/lib/indy/sandbox/pool_transactions_genesis
Pool config "identity_pool" has been created
indy>     pool connect identity_pool
Pool "identity_pool" has been connected
pool(identity_pool):indy>     wallet create actor_wallet key=abc
Wallet "actor_wallet" has been created
pool(identity_pool):indy>     wallet open actor_wallet key=abc
Wallet "actor_wallet" has been opened
pool(identity_pool):actor_wallet:indy>     did new seed=100A000000300000c0000000Steward1 metadata="steward DID"
Did "RnXJMDxifkBaceAkPizz8F" has been created with "~9F4P9aQysR1YATnARMuhxt" verkey
Metadata has been saved for DID "RnXJMDxifkBaceAkPizz8F"
pool(identity_pool):actor_wallet:indy>     did use RnXJMDxifkBaceAkPizz8F
Did "RnXJMDxifkBaceAkPizz8F" has been set as active
pool(identity_pool):actor_wallet:did(RnX...z8F):indy>     ledger nym did=RnXJMDxifkBaceAkPizz8F
Nym request has been sent to Ledger.

It works, but after publishing a few DIDs, or after a while, for some reason the command ledger nym did=<NEW_DID> stops working and gives a timeout error such:

Transaction response has not been received

But if I do:
ledger get-nym did=<EXISTENT_DID>

It still works properly from any of the nodes and I get the existent information about the DID:

pool(identity_pool):actor_wallet:did(RnX...z8F):indy> ledger get-nym did=RnXJMDxifkBaceAkPizz8F
Following NYM has been received.

I have checked my pool_transactions_genesis file and I’m sure it’s correct, as I can publish DIDs at some point, but suddenly I cannot anymore.
