Same problem.

I reviewed my logs again.  Actually, the SSL connections were not of the format IP:50002.  So, that hasn't changed since my server's last working state.  I upgraded Ubuntu to 18.04 LTS and upgraded to python 3.7 which increased the number of connections to approximately 30, but I could still not connect via an Electrum client.  Also, a couple months ago when I could connect I had about 10X the connections.  

Furo4kin, have you looked at these issues?
https://github.com/kyuupichan/electrumx/issues/556
https://github.com/kyuupichan/electrumx/issues/94

Let me know if your logs match any output from these issues.  Issue #556 seems to match the timeline of our problems.  I am unsure where the weakest point would be in a DOS attack, but I suppose it would be my router.

Furo4kin, if you would like any more info as I learn more, I could PM you if you allow messages from newbies

I found my laptop's IP address among the connections.  So, my client connects to the server, but the server does not serve any data to my laptop.  Presumably, I have a low connections count because clients see my server and connect to it but when they fail to retrieve data they connect to another server.

I ran electrum -v and figured out that the problem was my SSL certificate had expired.  For some reason, I could not connect in via port 50001.  So, unfortunately, anyone who has connected to my server in the past will not be able to connect unless (s)he deletes their wallet and restores from the seed because otherwise the old certificate will fail to verify.

I hope someone can help me.

I have some old Verge Electrum from which I only have the seed left.
I need to rebuild the wallet on OSX now so I downloaded Electrum-XVG2.4 from github and it runs fine, only its not connecting to the network.

The only server in it is electrum-verge.xyz
I only found electrum-xvg.stream as another server but theres no way to add it to the list.

Can anyone help me with an actual server list and how I can add them into Electrum-XVG2.4 so I can rebuild my wallet and recover my VERGE?

Thank you

I'm not hodling Verge but this 5-day old reddit post about offline electrum-xvg has some good feedbacks: A question about an ancient wallet
You need Tor for that.

Is there a current guide for setting up an Electrum server on a Mac (not a personal server)?

Is an Electrum Server the same thing as electrumx?  I hope that's not a dumb question.

I've been running a full Bitcoin Node (using the Bitcoin Core app) for a few months.

My goal is to set up BTC RPC Explorer and be able to look up my wallets, historical data, etc, on my own block explorer.

This is mostly a project for me to learn, strictly for my own use - at least for now.

Yes, that is one implementation of Electrum server.
And I'd recommend it if your end-goal is not to use it for personal use, but public.

Plus it's fork is maintained by same developers of Electrum: https://github.com/spesmilo/electrumx
For the set-up, you can refer to its official documentation: https://electrumx-spesmilo.readthedocs.io/en/latest/HOWTO.html

I don't know of any electrum SPC server that's ready to go for a Mac and I have very little experience with MacOS, but you may be able to compile a binary of Electrs (Romanz¹ or Blockstream²) that will run on your system.

ElectrumX is one of the SPC servers compatible with Electrum (and many other clients,) but as far as I know it's intended to run on Linux.  Again, if you're skilled with such things you can compile your own binary, but I don't know of any instructional that will guide you through the process.

Romanz Electrs is very easy to set up and plenty good enough for personal use with a blockchain explorer.  One of my servers has been running Mempool.space with Romanz Electrs as the backend, and it's been running flawlessly for nearly two years.  Looking up an address with a ton of transactions will be slow, but I've never had it hang up.  Blockstream's Electrs fork is more robust and more practical for a public server, but it requires more resources.

An interesting Electrum server is also Fulcrum which has been discussed in some other thread(s) here on this forum, e.g. here https://bitcointalk.org/index.php?topic=5441463 and also compared with other Electrum server implementations e.g. here https://www.sparrowwallet.com/docs/server-performance.html.

I use Fulcrum on my RaspiBlitz node as replacement for electrs because I got tired of the issues that electrs has sometimes with addresses that have a huge transaction history. For my personal Electrum wallets I don't need Fulcrum, electrs would be fine. When I do sometimes a bit of blockchain digging I've run into such issues from time to time with electrs. Fulcrum is easier to configure to serve huge address histories and it's refreshingly fast with data retrieval compared to electrs.

Linux and Windows executables are available from the Github, MacOS executables are announced but not yet there. You can always check the code and compile your executable yourself. I don't mind that the main dev appears to be in the BCH camp, the project is open-source and works very well for Bitcoin.
