The LTE Modem in my hAPLite LTE6 modem shows an upgrade firmware available but fails to download it. Tried rebooting several times but no change. Is anyone else having this issue ?
Thanks,

Anything being mentioned in log ?
I experienced the same problem as yours. If your LTE module version number ends in 01.03, then follow these steps to upgrade it manually to 01.04:
1. Download the firmware upgrade:
/tool fetch https://upgrade.mikrotik.com/firmware/FG621-EA/16121.1034.00.01.01.03/image
2. Install it manually:
/int lte firmware-upgrade lte1 upgrade=yes firmware-file=image
3. Delete the upgrade file after successful install:
/file rem image
I tried what you said. Even though the firmware check reveals an upgrade file, no file with that name seems to be able to download..even manually I you suggested.. Must be a Mikrotik issue..
The file from the link above downloads normally. The Mikrotik upgrade server is working, at least when accessed from my location.
Post the output of:
/int lte firmware-upgrade lte1
Hi,
I have a similar problem. New router launched, next updated to 7.13.3 and then I get a message about the new modem firmware.
It doesn’t work - update fails - “Couldn’t start - firmware URL not reachable (6)”.
But the ROS update check does not work either - “ERROR: could not resolve dns name”
So after updating to 7.13.3, something must have gone wrong in the configuration and the router has no access to the Internet.
That’s probably why the modem firmware update doesn’t work because the router can’t find the update
Where should I start checking, this is what it looks like:
Check DNS settings for starters.
If needed, manually add 8.8.8.8 or 8.8.4.4 to be 100% certain there is something which works (at least, it should).
The odd thing is that it does detect a newer version is available ?
I wanted to add a DNS client, but I don’t have the “lte1” option to choose from the interface list. If I choose “bridge” it does not work.
But when I set it to “bridge” and connected the Internet to the ETH1 port, the router had access to the Internet, downloaded and installed the modem firmware update
Ok, after several reset the configuration it is working now 
, I don’t know what was the reason but it works now - maybe there was a problem with the operator’s SIM card?
Anything possible. But when you do a reset-configuration, you’ll get the latest default configuration (e.g. 7.13). See the default configuration changes over time, so “your defaults” were based on whatever version was installed. By upgrading RouterOS, it keeps you config as-is and do NOT apply a NEW default configuration (unless you reset-configuration). And they’ve changed some defaults in 7.12/7.13.
I recommend folks getting a new LTE device FIRST upgrade to latest version, THEN reset the configuration to pickup the newer default configuration…ONLY then do any custom config. e.g. there have been a lot of changes to the defaults in recent versions, and using “old defaults” just invites problems IMO.
