When I use the command: ``` ./src/silkaj.py issuers 50 ``` I successfully get the result: ``` ### Issuers for last 50 blocks from block n° 41087 to block n° 41137 | uid | blocks | percent | |-----------+----------+-----------| | cgeek | 7 | 14.0 | | moul | 6 | 12.0 | | nay4 | 6 | 12.0 | | cler53 | 5 | 10.0 | | simille | 4 | 8.0 | | pafzedog | 4 | 8.0 | | inso | 4 | 8.0 | | kimamila | 3 | 6.0 | | gege53 | 2 | 4.0 | | hacky | 2 | 4.0 | | Jean-F | 2 | 4.0 | | charles | 1 | 2.0 | | gnu-tux | 1 | 2.0 | | vincentux | 1 | 2.0 | | modulix | 1 | 2.0 | | mmpio | 1 | 2.0 | ``` But if select a particular peer which is very close to me (same network) then I get a 503 HTTP error: ``` ./src/silkaj.py issuers 50 --peer cgeek.fr:9330 ``` ``` Traceback (most recent call last): File "./src/silkaj.py", line 54, in <module> manage_cmd(ep, c) File "./src/silkaj.py", line 32, in manage_cmd list_issuers(ep, int(c.subsubcmd), c.contains_switches('last')) File "/home/cgeek/dev/silkaj/src/commands.py", line 91, in list_issuers issuer["pubkey"] = request(ep, "blockchain/block/" + str(blk_nbr))["issuer"] File "/home/cgeek/dev/silkaj/src/network_tools.py", line 62, in request response = urllib.request.urlopen(request) File "/usr/lib/python3.5/urllib/request.py", line 163, in urlopen return opener.open(url, data, timeout) File "/usr/lib/python3.5/urllib/request.py", line 472, in open response = meth(req, response) File "/usr/lib/python3.5/urllib/request.py", line 582, in http_response 'http', request, response, code, msg, hdrs) File "/usr/lib/python3.5/urllib/request.py", line 510, in error return self._call_chain(*args) File "/usr/lib/python3.5/urllib/request.py", line 444, in _call_chain result = func(*args) File "/usr/lib/python3.5/urllib/request.py", line 590, in http_error_default raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 503: Service Unavailable ``` This is most probably because of Duniter HTTP limiter, which returns an error if a particular URL is called too many times in a second.
