I’ve been having problems with IJulia (old notebooks not working) and have fixed this before with a rebuild of my .julia directory. When I do ]add IJulia everything seem to be fine until I get an error with MbedTLS. Is there something I can do?

The error is

Had the same issue for v1.4, did you manage to solve the problem?

Hi @Haolin_Li, welcome! Could you please run the following code:

```julia
]add https://github.com/giordano/DebugArtifacts.jl.git
using DebugArtifacts
debug_artifact("MbedTLS")

```

This will _ **not** _ fix anything, but provide more information about what problem you’re experiencing

Thanks very much for your reply!  
I am a newbie to julia. The first line of your code does not work for me, it gives an error:

ERROR: syntax: unexpected “]”

Am I suppose to type each line of your code to the julia terminal?

Yes, sorry, `]` is the shortcut to enter the package manager mode in the terminal. If you want to run the code above in a script you can replace the first line for example with

```julia
using Pkg
pkg"add https://github.com/giordano/DebugArtifacts.jl.git"

```

Indeed, the connection has been refused, but this is strange:

```julia
curl: (7) Failed to connect to 127.0.0.1 port 1090: Connection refused

```

How come github is being redirected to your local host? I think you have some misconfiguration in your system.

Yeah, that’s definitely bizarre, I have no problem open the website in chrome. Probably because I used VPN before, but it still give the same error without using VPN.

Not sure it’ll help, but since you have Julia v1.4, you can try an alternative. Set the following environment variable

```nohighlight
export JULIA_PKG_SERVER=https://geo.pkg.julialang.org

```

restart Julia (make sure this setting is correctly seen in Julia with `ENV["JULIA_PKG_SERVER"]`) and try again.

Anyway, the best way forward is to fix the network configuration of your system (did you try to reboot after switching the VPN off?)

Hi, probably it is because of the regional block, I am able to download with wget and VPN on:

```julia
 wget https://raw.githubusercontent.com/JuliaBinaryWrappers/MbedTLS_jll.jl/master/Artifacts.toml 

```

Did you try using the PkgServer as I suggested above? That doesn’t go through GitHub

[EDIT: see next comment, I was just trying to help here, but maybe wasn’t hastily looking into this.] There are many similar questions, ~~I think this is a Windows-only problem (I can’t replicate on Linux) and this may be helpful:~~

[IJulia install issue - #15 by derekmahar](https://discourse.julialang.org/t/ijulia-install-issue/45037/15) and [MbedTLS 1.0.2 failed to load on Julia 1.5.2 (solved by downgrading to MbedTLS 0.7.0)](https://discourse.julialang.org/t/mbedtls-1-0-2-failed-to-load-on-julia-1-5-2-solved-by-downgrading-to-mbedtls-0-7-0/47430) ~~and [IJulia install stops for MbedTLS error](https://discourse.julialang.org/t/ijulia-install-stops-for-mbedtls-error/37974)~~

@Palli please continue to [IJulia Installation Problem - MbedTLS Error](https://discourse.julialang.org/t/ijulia-installation-problem-mbedtls-error/48198) (and I don’t think any of the threads is related, including the last one which is this one itself…)
