I hope you've worked it out by now, and hopefully you've worked out a more secure solution than I did, but the way I got around this was to disable SSL certification on the conancenter remote.

conan remote remove conancenter
conan remote add conancenter https://center.conan.io false

i am sorry, i am complete your command and have same error( What version you build?

This has probably something to do with https://conan.bintray.com getting no more new packages after July 1st 2021: Conan Blogpost here.

With these conan settings:

$ conan remote list
conancenter: https://center.conan.io [Verify SSL: True]
conan-center: https://conan.bintray.com [Verify SSL: True, Disabled: True]

I can find the libcurl module

$ conan search libcurl/ue4@adamrehn/4.27
Existing packages for recipe libcurl/ue4@adamrehn/4.27:

    Package_ID: 4a8aa5a92eca740ec3100060d2a1f829bb028521

hogsy9 already briefly mentioned how to change the conan repository:

I hope you've worked it out by now, and hopefully you've worked out a more secure solution than I did, but the way I got around this was to disable SSL certification on the conancenter remote.

conan remote remove conancenter conan remote add conancenter https://center.conan.io false

@iwer

@iwer Thanks for your reply,I had try these conan setting:

$ conan remote list
conancenter: https://center.conan.io [Verify SSL: True]
conan-center: https://conan.bintray.com [Verify SSL: True, Disabled: True]

But I still got:

conan search libcurl/ue4@adamrehn/4.27
ERROR: Recipe not found: 'libcurl/ue4@adamrehn/4.27'

ERROR: Failed requirement 'libcurl/ue4@adamrehn/4.27' from 'gdal-ue4/2.4.0@adamrehn/4.27'
ERROR: Unable to find 'libcurl/ue4@adamrehn/4.27' in remotes

and then I also had try these conan setting:

$ conan remote list
conancenter: https://center.conan.io [Verify SSL: True]
conan-center: https://conan.bintray.com [Verify SSL: True]

then I got a different problem:

Unable to connect to conan-center=https://conan.bintray.com
1. Make sure the remote is reachable or,
2. Disable it by using conan remote disable,
Then try again.

I also try to disable SSL certification ,but still got the same problem.

Wait just remembered: libcurl gets wrapped in a conan package from UE4 thirdparty libraries...
Did you by chance forget to generate the wrapper packages?

$ ue4 conan setroot <UE4 Root directory>
$ ue4 conan generate
...
Generating and installing wrapper package for libWebSockets...
Generating and installing wrapper package for libcurl...
Generating and installing wrapper package for libstrophe...
...

@iwer

@iwer Thanks for your great help again,I'm using an installed build of ue,and i don't check the generate information carefully,after i build the source code, the problem has been solved, thank you so much
