failed connection to uniprot

Hi there,

I am trying to download the updated databases for alphafold2 on the cluster ComputeCanada.

Some of them to work need to connect to uniprot, but the connection fails.
For example when I tried
```
bash download_uniref90.sh $SCRATCH/alphafold/data
```
I received the error message:

```
--2025-03-30 20:31:02-- ftp://ftp.uniprot.org/pub/databases/uniprot/uniref/uniref90/uniref90.fasta.gz
=> ‘/scratch/avim2701/alphafold/data/uniref90/uniref90.fasta.gz’
Resolving ftp.uniprot.org... 128.175.240.195
Connecting to ftp.uniprot.org|128.175.240.195|:21... failed: Connection refused.
```

This is happening for the last few days and for every single script that invokes a connection to uniprot.
Needless to say I contacted ComputeCanada to ask about this problem but they told me it is not a problem related to them.
Can you help me?
Thank you very much.
Best,
Mariano
