Did you specify that IP address in the config file? Did you try just using 0.0.0.0 and see if it would bind then?

I defined host = with the  FQDN and it took the IP from this information.
If I use localhost then I don't have any error but from what I understand than none can connect.

Well that gives no error but now it won't be available from the outside, right? :-(

It now works.
I had to set
Code:
host = 0.0.0.0
report_host=fqdn
Thanks to dan91 and hsmiths on #electrum


A new electrum server node says hello world!

hostname: e1.ueo.ch
network: IPv4
ports: 50001
prune: 10000
location: Germany


I will add more ports in the near future.

Public SSL Cert Bug?

To experiment with some inspiration from this thread, I got a public SSL cert from Let's Encrypt and I hit a slight glitch. The client wouldn't sync after switching to the public cert, and deleting the cached cert fixed it. I've since reverted back to self-signed to prevent collateral damage until this issue is hashed out.

I haven't spent much time debugging as it's late for me, and a quick skim through the code doesn't get me anything. So far I've found that only Electrum 2.0+ is supported in the server setup guide.

Thoughts?

Public SSL Cert Bug?
There is currently no way to replace a self-signed certificate because it is pinned by all the clients who ever connected.

To go to a CA-signed certificate you need to also change your DNS name so that your server will have a new identity.

About a day ago I did this with one of my electrum servers, and though it is taking connections, the traffic is much lower than it used to be. This is partly because Electrum clients prior to 2.0 cannot connect at all with a CA-signed certificate, but mostly because it takes a while for everyone to discover the new server.

BTW, I got my cert from StartSSL and to make it work I had to append the intermediate CA bundle to the end of my .crt file.

Just as a side-note: I used to use StartSSL, too. But compared to the new letsencrypt it's a lot of hassle and seems complicated in comparison.

Are there any news about server re-write, with faster block processing?

Been a couple of pull requests that have gone through from JAuthor that have increased the speed a little bit.

Please explain how you used letsencrypt with electrum-server.

Fireduck re-wrote electrum-server in Java and it processes blocks much faster than the original Python version.

The fact that there are less than 50 servers scares me quite a bit.
What happens if all the Electrum servers go offline?

If all 50 servers disappear, you can still set up your own Smiley

And with that one I can then send my BTC to a non-light wallet, by making a last transfer from Electrum to another BTC address, right?

OK, thank you Smiley
However, aren't 50 server a bit few?
I mean, I didn't have performance problems up to now, but in the future?

If you want a network that will pay the w nodes rather than only the miners.   Then you have dash.   Otherwise we can fork the client source code to pay to the electrum server as well as the miner fee.  Only people who are both savvy enough to use github and who care about the electrum server count enough would ever use such a client though.  There are other light clients out there that don't use electrum servers.   These clients have to do more work.

I am concerned about transactions with 0.1mBTC for a transaction not getting through.  If the user must add another 0.1mBTC, the users might decide to go with some other light client.
