Error updating to latest version of MC

[crawlem]

During start.sh I see the following error, which prevents the server updating to the latest release (and therefore stops my clients connecting as they have successfully updated).

Checking for the latest version of Minecraft Bedrock server ...

curl: (3) URL using bad/illegal format or missing URL

It looks like maybe the https://www.minecraft.net/en-us/download/server/bedrock page has changed, breaking the code which checks to see what the latest version is?

Hey crawler and TheRemote -

I am also having this issue and looked pretty deep into it. I am a bash novice but my understanding is that Minecraft.net was modified to load the content dynamically which broke curl. I fixed the issue, though, by modifying start.sh to curl this page instead:
https://net-secondary.web.minecraft-services.net/api/v1.0/download/links

I'd suggest that as a temporary workaround if not a potential fix to the GIT repo.

Cheers!

I am having the same issue, the link has not changed by the looks of it, but something internal has which is preventing curl from downloading the file. Not sure if there is a third party site hosting separate download links that we can use.

[ywingdriver]

@TylerJohnson177 try https://net-secondary.web.minecraft-services.net/api/v1.0/download/links - that's a page from the Minecraft API that returns the links. No clue if that will stay active at that link though.

[TylerJohnson177]

Is it possible for someone to upload their start.sh file with those modifications, because I am confused lol. I am ot sure where in the file to update the link, and which links to update.

Here is the part of the script that updates the server

`# Retrieve latest version of Minecraft Bedrock dedicated server

Replace the line after

# Download server index.html to check latest version

(this line:)

curl -H "Accept-Encoding: identity" -H "Accept-Language: en" -L -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.$RandNum.212 Safari/537.36" -o downloads/version.html https://www.minecraft.net/en-us/download/server/bedrock

with this new line:

curl -H "Accept-Encoding: identity" -H "Accept-Language: en" -L -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.$RandNum.212 Safari/537.36" -o downloads/version.html https://net-secondary.web.minecraft-services.net/api/v1.0/download/links

Then run stop.sh and then start.sh (if you're on Ubuntu you can just right click the files and hit 'run as program'.) I believe restarting the server should also work but that's what I did.

Those steps are what worked for me anyway - definitely save a backup of the original start.sh in case that doesn't work.

UPDATE:
For anyone who's interested in what this line does the original script downloads the page at https://www.minecraft.net/en-us/download/server/bedrock and saves it at the file location downloads/version.html in your Minecraft server folder. It does this so it can grab the URL of the bedrock server from the page. Unfortunately Microsoft has modified the page and so the link isn't downloaded anymore. The new page I've modified the script to download instead (https://net-secondary.web.minecraft-services.net/api/v1.0/download/links) I found by scouring the loaded network files at the suggestion of ChatGPT. Thankfully it's a publicly accessible JSON API endpoint so we can download it instead of the other page because it has the link to the bedrock zip file in it. Hopefully this endpoint will keep getting updated by Microsoft so it will be a reliable way to get the newest edition of the bedrock server.

[TylerJohnson177]

That worked, thank you very much.

[POWerSUrgeSW3]

Thanks everyone for bringing this up! I kind of figured Mojang updated the URL when my client version updated yesterday, but re-running the Instances on my Minecraft Server were still stuck on v1.21.84.1.

Created new 'start' scripts and now added them to my maintenance script I created. So I can manually run these as needed until an updated SetMinecraft.sh script is pushed.

[QuimaxW]

As a simple workaround, you can add a version pin with the current version:

echo "bedrock-server-1.21.92.1.zip" > version_pin.txt

Then, simply stop & start the server.

[Daniel-Research]

All right, here we are once again, the script needed some care.

As @ywingdriver advised, I updated the script with the new line to get the links. But the script still failed to work, since it could not extract the info we needed.

With the help of Gemini AI I managed to made it work.

After the

# Download server index.html to check latest version

section I replaced with the following code:

curl -H "Accept-Encoding: identity" -H "Accept-Language: en" -L -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.$RandNum.212 Safari/537.36" -o downloads/version.html https://net-secondary.web.minecraft-services.net/api/v1.0/download/links
LatestURL=$(grep -o '"downloadUrl":"https://www.minecraft.net/bedrockdedicatedserver/bin-linux/[^"]*"' downloads/version.html | \
            awk -F'"' '{print $4}')
LatestFile=${LatestURL##*/}

I hope it helps. At least for a while :)

[TylerJohnson177]

This issue might have surfaced again. It seems like

https://net-secondary.web.minecraft-services.net/api/v1.0/download/links

returns this:

{"namespace":"ServiceRuntime","code":"InternalServerError","message":"Response status code does not indicate success: 404 (The requested website is not configured.).","customData":{}}

Not sure if there is another alternative link that can be used.

[TheRemote]

Hmmm, I am definitely seeing it. I tried going to the official web site (to see if the URL had changed and what it might be) and also can't download it from the official web site:

https://www.minecraft.net/en-us/download/server/bedrock#

When I go there and click Download for Linux it just keeps opening a new tab and nothing happens.

I opened my browsers developer console with F12 and saw this URL in the console still giving a 500:

https://net-secondary.web.minecraft-services.net/api/v1.0/download/links

It almost looks like someone wiped their VMs that serve the download files (probably on accident). Even on the official site though I'm not able to get it at the moment!

[TylerJohnson177]

I noticed that as well. The only reason I found out was because I modified the script so it fully deletes the behavior_packs/resource_packs/definitions directories and replaces them with the newer version when an update installs. (Had an issue where outdated vanilla packs were causing weird behavior)

It detected an update when there was none and all 3 of those directories got removed and were not replaced, which prevented the server from even running after a scheduled restart.

I was able to get my server fixed just by adding a version_pin.txt with the latest version.

Hopefully this is something that will be resolved on Mojang/Microsoft's end.
