error code 502

Barrowman — Fri, 29 Aug 2025 16:39:06 GMT

“Hi, my website is showing a 502 Bad Gateway error when I turn on my laptop. Is it possible to check if the server is down or if there’s a misconfiguration on your end?” I get the same message on my iPhone.

I'm an 81 year old if anyone can help in laymens terms it would be appreciated. Thank you. Oh, and I have full fibre 150.

@Barrowman, thank you for bringing this to our attention. Just to double check on other things. If I may kindly ask, apart from that particular website, are you able to access other websites?

Hi, Yes, after the initial wait while the error code goes the laptop then restarts as normal and I can use all web sites as usual, but, if there are links in the websites they dont work anymore.

Here is an example....

"pottersleisure2.acemlnb.com’s DNS address could not be found. Diagnosing the problem."

DNS_PROBE_POSSIBLE

I understand and I really appreciate for you giving out a helping hand on your end with this.

@Barrowman, how's your browsing history? I will kindly ask for you to try clearing your browser history, access the site once more and re-try accessing the link that's giving you issues.

Kindly confirm with feedback once done.

Deleteing History made no difference. I just checked my phone and it says the following.

Password Incorrect

Enter the password for the iMap account

"My Mail" account

This is when you are trying to connect to your internet? Correct?

No I just hit the "Cancel" button on the flag and the internet works fine..

Thank you for confirming with feedback @Barrowman as I now assume that it's the links you are trying to access that are giving you issues when accessing since the internet works fine. Correct?

Re: error code 502

No, I refer you back to my original post. It's when I first turn my laptop on it comes up with the message and I then have to wait for it to re-boot itself then the internet works - the links in mail still wont work either...

Good morning. Yes The problem has not been resolved.

A bit of extra info just got this morning.....

"CMOS checksom is invalid - CMOS reset (502)"

Perhaps you could advise if this may be a problem with my pc. Thanks

Re: error code 502

nomfezeko-TT — Mon, 01 Sep 2025 09:57:43 GMT

Thank you for providing the additional information. The message "CMOS checksum is invalid - CMOS reset (502)" typically indicates an issue with the BIOS settings on your PC, which can be related to the CMOS battery. This battery helps retain BIOS settings when the computer is powered off.

Here are a few steps you can take to address this issue:

Check the CMOS Battery: If your PC is older, the CMOS battery may need to be replaced. This is usually a CR2032 battery located on the motherboard.

Reset BIOS Settings: You can try resetting the BIOS to its default settings. This can often resolve checksum errors. You can usually do this by entering the BIOS setup during startup (often by pressing a key like F2, DEL, or ESC) and selecting the option to load default settings.

Update BIOS: If the problem persists, consider checking for a BIOS update from your motherboard manufacturer’s website. An update can sometimes resolve underlying issues.

If you're not comfortable performing these steps or if the problem continues after trying them, please let me know, and I can assist you further.

Thank you, I look forward to helping you resolve this issue!

Hello again. Sorry it's been a while as I had to wait for help from my son. he has tried all you surgested but

was unable to resolve the issues, the only thing he couldn't do was to reset the bios to the default setting

as that did not appear as you surgested it would when entering the default settings page.

Hi there @Barrowman, I'll need you to check if you have any ad blockers installed on your devices as that too can be the course. I'll be investigating in the meantime on my end while you check on that. Thanks

Re: error code 502

Barrowman — Fri, 05 Sep 2025 09:51:29 GMT

Hi, yes I have Adblock+ I've had that for three years now without a problem, also the add blocker

that comes with the eero system...

Re: error code 502

siphosethu-TT — Fri, 05 Sep 2025 09:54:55 GMT

Can you block the one you've had for 3 years to test if maybe that's the cause. Thanks

Re: error code 502

Barrowman — Fri, 05 Sep 2025 13:16:06 GMT

I've gone one better, I've completly uninstalled it. I'll re-install when I need it again.

No problem, please reboot the devices and try accessing the links again. Thanks😇
