 - Even so, there are still 52 items with incorrect filenames, so I can't derive their PDF URLs...
   - For example, `Wild_cherry_Prunus_avium_859.pdf` is here (with double underscore): https://www.bioversityinternational.org/fileadmin/_migrated/uploads/tx_news/Wild_cherry__Prunus_avium__859.pdf
 - I will proceed with a metadata-only upload first and then let them know about the missing PDFs
+- Troubleshoot an issue we had with proxying to the new development version of AReS from DSpace Test (linode19)
+  - For some reason the host header in the proxy pass is not set so nginx on DSpace Test makes a request to the upstream nginx on an IP-based virtual host
+  - The upstream nginx returns HTTP 444 because we configured it to not answer when a request does not send a valid hostname
+  - The solution is to set the host header when proxy passing:
+
+```
+proxy_set_header Host dev.ares.codeobia.com;
+```
+
+- Though I am really wondering why this happened now, because the configuration has been working for months...
+- Improve the output of the suspicious characters check in [csv-metadata-quality](https://github.com/alanorth/csv-metadata-quality) script and tag version 0.2.0
