@nostrdev please upvote https://forum.cloudron.io/topic/14231/ccai-cloudron-custom-app-installer

[nostrdev]

done! we would like to add that the packaging team should prioritise the custom app installer over btcpay server (as we can easily deploy apps using the package installer from that point onward)

What is the latest news on official support for BTCpayserver on Cloudron?

@nostrdev I'm trying to install btcpayserver after installing btc-core (and node fully synced)

I change the rpc auth in btcpayserver config.yml to match what is in btc-core bitcoin.conf

I restarted btcpayserver

I get a blank page on btcpay.domain.tl in Safari and a 500 error in Firefox.

btcpayserver logs :
Jan 07 16:57:24 fail: Microsoft.AspNetCore.Server.Kestrel: Connection id "0HNIE1J43J819", Request id "0HNIE1J43J819:00000001": An unhandled exception was thrown by the application.

I tried to set sysctl values but they're in RO location so will need a rebuild if wrong

Am I doing something wrong ?

@timconsidine awesome, how much space does btc-core take up fully synced?

[nostrdev]

@timconsidine when you say the config matches, you mean this part right?

# Bitcoin RPC Configuration
bitcoin:
  rpc_user: "bitcoin"
  rpc_password: "xxxxx"

Note that the rpc_password should be the actual password, NOT the rpcauth= value in the bitcoin.conf file (which is derived from the password)

@robi for info, this is a non-pruned (full) node, as of today:

root@d1f00579-9662-4a14-896e-cf7cd8127709:/media/core# ls
banlist.json  bitcoind.pid  blocks  chainstate  debug.log  fee_estimates.dat  peers.dat  settings.json
root@d1f00579-9662-4a14-896e-cf7cd8127709:/media/core# du -sh
766G    .

@nostrdev thanks, good to know.

You know the next question..

Pruned?

And is it sync-able already pruned?

I can't install it if it's not..

[timconsidine]

@robi I pruned mine to 3Gb
I think somewhere I read pruning down to 600Mb might be possible. Maybe not lower.

[timconsidine]

@nostrdev thank you

Yes, I used the password value printed below that line as a comment.

I will dig bit deeper later
