My Wowlet is capable of syncing with both remote and local nodes, but can't seem to fetch the other "metadata". As a consequence I can't see the fiat prices, price history nor any of the forum or Reddit posts in the wallet. How do I fix this?

It works for sending and receiving but think the server is down for the info or something along those lines.

[terrydavis]

That could very well be it, looks like that server URL was already changed in https://git.wownero.com/wowlet/wowlet/commit/9c58913ee2377ebaf1e2a3b7e946b57e29d37935. Fortunately this server seems to be open source at https://git.wownero.com/wowlet/wowlet-backend/, perhaps it's possible for someone from the community to host?

[terrydavis]

I looked into getting the server working, and suffice to say it was tough. Right now I am unable to get the production "edition" to run in Docker, but I was able to use the redis and tor setups provided in the docker-compose.yml to start the development "edition" in a Python virtualenv on my native Artix. Here's the patch:

For anyone who wants to try this out, you'll have to build Wowlet yourself (fortunately there were no problems here, the process is documented in the repo) making sure to edit src/appcontext.h as so:

While it's not as good as the Docker instance of the backend just working, this is still better than nothing as I do now have exchange rates and historical prices in my Wowlet. For reference, here's what happens with the backend in Docker:

Long-term, I think the backend stuff should be moved into Wowlet itself to prevent issues like this from happening ever again.

[nogoer]

since you sem to be the most recent post im replying to you with a question. Is this coin still active? On a whim i decided for fun to try and mine this coin and started with trying to setup my own node. After finding way outdated info on that and having no success i just decided to try mining to the deamon which i got working. Now im not sure its even worth this, theres no pools left and after 3 days of mining ive had 0 results(sort of expected), but not sure if thats because of low hash or defunct coin. There seems to be very little current info on how to properly mine or setup a node yet the coin is still listed on exchanges and seems to have mem activity.

Whats the deal currently with mining wownero?

Don't thread hijack please.

There's no pools left because Wownero is solo mine only since Junkie Jeff and you should really avoid mining with the daemon, I compared it with XMRig (both 10 threads, although my CPU can do 20 just fine) and the daemon is 10 times slower than XMRig (~700H/s vs ~7000). For reference, according to https://www.cryptunit.com/coin/WOW?hr=7000 I would get a block every approx. 7 days with XMRig and every approx. 69 days with the daemon.

P. S. I'm not currently mining Wownero myself, these were just short benchmarks.

[terrydavis]

Well, I figured out what was up with the backend and made a PR to fix it: https://git.wownero.com/wowlet/wowlet-backend/pulls/21
