What do you recommend?
to upgrade the memory to 16G
now I assume you have only 8G
on that specific one I had 4gb, just upgraded to 8gb. Lets see how that works out. I will keep you updated.
I have another fresh installation with 8gb currently syncing. It is at about 58%, but will not be ready to report on that one till the morning.
hmm 4G not enough for sure, let’s see with 8G how it’s working

FYI - been battling this for a few days (and a few other self induced issues). Went from 4G t3a.mediums on AWS to t3.XL’s. Instantly solved. Thanks Alexd1985

Looks like it is working now! Thank you @Alexd1985. I will continue setting up the node and will update all of the results.

I strongly recommend you walk away from the t3* instance and move to the m5a or c5a.
Also add swap to your 8gb memory instances.

Thanks for the suggestion, just getting them back up right now, but reviewing the instances and reserved options from AWS is certainly on the list for later.
I had the same problem, thank you for fix it!
But there is something witch I dont understand:
my node starts to work files without mainnet- prefix, but with the new files has it and I dont have to modify the env file. Why?
because env file has default values for config files - or have you specified path to the files?
#CONFIG="${CNODE_HOME}/files/config.json" # Override automatic detection of node config path
#TOPOLOGY="${CNODE_HOME}/files/topology.json" # Override default topology.json path
how does your env file look like?
yes, but I have to add the mainnet prefix before config.json and works well with the new json files.
BTW i think replacing the topology.json is not needed to fix the problem.
I had the same issue, stock on epoch 207 @99.9%
THANK YOU for this response. the guide encourages you to change the external IP with no warning of waiting for it to sync based on the downloaded mainnet-topology.
Still have the issue?
No Sir, I re-download mainnet-topology and am keeping it pointing to ihok and not the relay IP, until it syncs to 100%. All is working thank you!

Hey! I’m having the same issue.
I have a raspberry pi with 8 gb of ram + 4 gb of swap. I followed CoinCashew guide but relay resets at epoch 207, it deletes the socket and doesn’t sync anymore. I can get it running again by deleting the db folder and restart the service. But that only works until it gets to 207 again… .gLiveView says “Could Not Connect to a Running Instance, 3 Failed Attempts in a Row!”
I’ve tried downloading the mainnetfiles, but the issue remains.
I followed htop until the moment it resets and both memory and cpu seem fine.
I’ve tried changing, as @Alexd1985 proposes, the ShelleyGenesisHash in mainnet-config.json from the “67f10…” to “1a3b…” but a logged error demands I change it back to “67f10…” or it doesn’t continue syncing.
Any ideas? Much appreciated!
Re-download the files for mainnet and reset the node
I have already tried deleting the mainnet files, then doing
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-config.json
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-byron-genesis.json
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-shelley-genesis.json
wget https://hydra.iohk.io/build/6198010/download/1/mainnet-topology.json
then deleting the db, then restarting the node. It still breaks, after 12 hours~, at epoch 207.
Mmm, I’m know realising I only did that for the relay, will doing it to the BP help?
Type sudo journalctl -e -f -u cardano-node
Do not delete the db
