My Bambu Lab slicer keeps giving me the message “User information has expired, please log in again” and a link. Clicking the link takes me to the Health Management System home page where I can try and login, but, yes, my login details do not work. It asks me to reset password, I supply my email address and it says to check my inbox to reset my password.
But no email arrives.
I have tried several times
Any ideas?
Welcome to the forum.
Short answer
Follow the instructions for solving your problem:
HMS_0500-0300-0002-0055: User information has expired. Please log in again.
Detailed Answer
The error message appears on the HMS (Health Management System) tab of the printer, so when you press the link, you are directed to the HMS home page of the Bambu Lab Wiki.
You shouldn’t try to log in to that webpage; the HMS is a Bambu Lab function that facilitates troubleshooting by listing error messages and codes with links to the solution procedures.
Different methods exist to use it, depending on the type of info you get (error message, error code, QR code). In this case, since you only have a message prompt, you can do, for example:
Press: ctrl+F (winOS) or cmd+F (macOS)
Write the message prompt (or part of it) in the search box:
And you’ll find your error in the HMS Home page:
Press the link respecting the error, and you will be redirected to a page with further info and instructions.
i get this message. I have x1C. I go to settings, on printer, I am logged into the wifi. no error there.
i go to account, i am logged into account (no error there) I go to the phone app, the directions say to BIND THE PRINTER, but that option does not exist on the app.
this is nuts. nothing looks disconnected, but this keeps popping up.
any way to clear this?
Getting the same issue after updating to the latest firmware, despite still being logged in.
I logged out on my desktop and in Bambu handy and the error persists, despite everything working fine and me clearly being logged in.
Can’t find anyway to clear this.
Same issue. Did all the things, same error, but otherwise it acts normally and I’m connected to my account. X1C, Handy and Studio all on latest firmware/software.
I’m seeing the same error message on the same device and also suspect it’s related to a firmware update. However, simply turning the printer off and back on usually clears the error - at least until it reappears. I’ve started to ignore it, since it doesn’t actually affect the printer’s usability.
In general, I’ve noticed that updates occasionally cause odd error messages. This is most likely just coincidence and not an attempt to boost spare parts sales.
I have the same issue. Everything is working just fine, but the error is still reported. Switching off and on again has no effect. Sigh!
Same here. Any official fixes for this?
any update on this - it’s NUTS, shows on my phone, and on the bambu printer, but everything seems to be logged in correctly.
Same here: Everything looks OK, but the error won’t go away. Trying to follow the HMS help page: According to it, I am logged in, so…
I’m not real worried, since everything works fine, but it is annoying!
ChatGPT told me this, it worked for me…
C:\Users\<yourname>\AppData\Roaming\BambuStudio
(You can rename it to BambuStudio_old if you want to keep settings.)
3. Reopen Bambu Studio — it’ll ask you to log in again.
Facing this exact issue. The error appears everywhere: printer, bambu studio and android. But everything is logged in. What’s the catch?
Same problem here on both X1C printers. H2D does not have this issue. Same Bambu Studio, all logged in and working. Just have this message on my X1Cs and the health warnings are not popping up.
Happened w/ a recent firmware update. 
Tried the above and it didn’t work.
Any other suggestions on how to solve this?
Did not help me, but made it worse 
I was able to log in, and had to re-configure everything from the very beginning. Worst issue: I was not able to work on any model. When selecting anything on the screen, Bambu Studio shut down…
Luckily I did not delete the original settings…
Same issue here tried logging in and out resetting network etc
Also getting this as of today… I have so many issues updating the X1C this is why I avoid updates like the plague. This has been happening since September it seems yet no fix, amazing.
Update: In case anybody is still struggling with this, I finally got this error to clear by logging out, and logging back in at the printer itself. Have had this error for months, and it now worked on both of my X1Cs. I tried this same procedure months ago and it did not work, but now it does for some reason.
this just worked for me as well thankyou for the post been driving me nuts seeing trhe lil red dot for a week or so lol
Thanks, worked for me as well!
Thank You, this worked for me. Finally got rid of the red dot.
