When forge checks for the latest version of my mod it doesn't work. I tested it by changing the version of my mod on eclipse to a different one. I looked at the log and got this:

 

[21:33:45] [Forge Version Check/INFO] [ForgeVersionCheck]: [Forge] Starting version check at http://files.minecraftforge.net/maven/net/minecraftforge/forge/promotions_slim.json
[21:33:45] [Forge Version Check/INFO] [ForgeVersionCheck]: [Forge] Found status: BETA Target: null

My update.json (on github and I didn't use gist)

"homepage": "http://minecraft.curseforge.com/projects/modrops/files",
  "promos": {
    "1.8.9-latest": "0.3.0_2",
    "1.8.9-recommended": "0.3.0_2",

    "1.10-recommended": "0.5.3"
    "1.10.2-latest": "0.5.2"
    "1.10.2-recommended": "0.5.2"
  },
  "{MinecraftVersion}: {
    "1.10: {
        "0.5.1": "Added netherrack drop for nether quartz ore. Fixed the adaptive egg recipe. Started work on the custom villager: Biomaker.
Mostly done but has only four trades."
    }

1) Why does your URL container {}? Thats not a valid url

2) Your json is broken. See the red errors when you view the page

3) You need to use the raw links.

i have a problem with forge. i have the latest version

Please do not add on to a thread someone else started just because you think your issue is the same, changes are it is not.

You should start your own thread.

i have the latest version

No you don't, the latest version is 1.15.2-31.2.0 and you are still using 1.12, which is no longer supported due to age.

Please update to a modern (1.14.4/1.15.2) version to receive support.

 

More information on supported versions can be found in the LTS link at the top of every page.
